In the summer of 1977, a quiet revolution was brewing in a modest home in Burlington, Vermont. It did not begin with a grand political manifesto or a high-tech corporate laboratory. Instead, it began with a universal, yet unspoken, physical agony. As the running boom of the 1970s swept across the United States, thousands of women were taking to the streets, parks, and tracks, eager to claim their share of the athletic landscape. Yet, with every stride, they encountered a painful, embarrassing, and seemingly insurmountable obstacle: their own bodies. The lingerie market of the era offered only two options—delicate, unstructured lace that provided zero support, or rigid, wired contraptions that dug into the skin and chafed until it bled. For the active woman, movement was synonymous with pain.

The story of the sports bra is the story of how a single, deceptively simple garment unlocked the athletic potential of half the world’s population. Prior to its invention, women’s participation in sports was restricted not just by societal prejudice and institutional barriers, but by the literal hardware of their clothing. The creation of the first "Jogbra"—cobbled together from two jockstraps stitched together in a basement—did more than solve a biomechanical problem. It dismantled a physical barrier to entry. By providing comfort, security, and pain-free motion, this run-of-the-mill piece of underwear became an instrument of liberation, allowing women to run farther, jump higher, and compete harder than ever before.

This book is a narrative history of that extraordinary invention and the cultural earthquake that followed. It takes readers behind the scenes of the 1977 breakthrough, introducing the trio of visionary women—Lisa Lindahl, Polly Smith, and Hinda Schreiber—who refused to accept the status quo. Through their ingenuity, grit, and grassroots determination, they bypassed a skeptical, male-dominated sporting goods industry to build an entirely new product category. In telling their story, Unbound explores how this single piece of apparel catalyzed a multi-billion-dollar activewear industry, paved the way for modern athleisure, and reshaped the retail landscape forever.

Beyond the business and the science of biomechanics, Unbound examines the profound cultural shifts that the sports bra set in motion. The garment did not just support breasts; it supported a massive paradigm shift in how society viewed women’s bodies. For generations, the female form in motion was sexualized, pathologized, or shrouded in shame. The sports bra helped redefine the female body as an instrument of strength, speed, and athletic agency rather than an object of aesthetic appreciation or domestic utility. From the basement prototypes of Vermont to Brandi Chastain’s iconic, celebratory shirt-whip at the 1999 Women’s World Cup, the visibility of this garment marked a reclamation of physical space and public pride.

For readers today, the sports bra is so ubiquitous that its existence is taken for granted. Yet its journey from a radical, fringe experiment to an artifact housed in the Smithsonian Institution is a testament to the power of everyday innovation. Unbound offers a gripping look at the intersection of gender politics, design technology, and athletic history. It is an inspiring reminder of how courage, necessity, and a bit of DIY resourcefulness can quietly alter the course of history, freeing generations of women to move, compete, and live without limits.

In the mid-1970s, an unusual phenomenon took hold of the American landscape. Across the country, ordinary citizens who had spent decades riding in station wagons, sitting on porch swings, or lounging in armchairs suddenly got up and started running. They did not run because a doctor had warned them of impending cardiovascular doom, nor because they were training for the Olympic Games. They ran because a strange, collective madness—or perhaps a sudden, infectious yearning for physical freedom—had seized the nation.

This was the dawn of the great American running boom, a cultural tidal wave that transformed jogging from an eccentric, fringe pursuit into a mainstream obsession. Almost overnight, municipal parks, quiet suburban cul-de-sacs, and busy city streets were populated by legions of men and women huffing, puffing, and sweating in the open air. The sidewalk, once merely a path to get from point A to point B, had become an athletic arena.

To understand how monumental this shift was, one must look at the landscape of American fitness prior to this decade. For the average adult, vigorous exercise was something left behind in high school gym class. The prevailing wisdom suggested that after a certain age, strenuous physical exertion was not only unnecessary but potentially hazardous to one’s health, particularly for women. If adults exercised at all, they did so in the privacy of their homes, perhaps performing a few modest calisthenics on a living room rug while following along with Jack LaLanne on a black-and-white television set.

The idea of putting on canvas sneakers, stepping out the front door, and deliberately running several miles until one’s chest heaved and sweat poured was considered downright bizarre. Early joggers in the late 1960s reported being stared at, yelled at, and occasionally chased by stray dogs or suspicious police officers who assumed that anyone running in public must be fleeing the scene of a crime.

Yet, by 1977, an estimated twenty-five million Americans had taken up running. The sport’s sudden, explosive popularity was fueled by a perfect storm of cultural, political, and literary forces. Chief among these was the publication of The Complete Book of Running by James F. Fixx in 1977. Fixx, a formerly overweight editor who had transformed his own life through the sport, wrote about running not as a grueling chore, but as a path to spiritual enlightenment, mental clarity, and physical rebirth. His book spent months at the top of the bestseller lists, convincing millions of readers that they, too, could find salvation in a pair of running shoes.

At the same time, charismatic American distance runners like Frank Shorter, who won the gold medal in the marathon at the 1972 Munich Olympics, and Steve Prefontaine, the defiant, mustache-sporting rebel of the track world, captured the public’s imagination. Shorter’s victory, broadcast live into millions of American living rooms, made distance running look cool, attainable, and deeply patriotic.

For men, joining this revolution was relatively simple, at least from an equipment standpoint. A man who wished to run needed only to purchase a pair of nylon shorts, a cotton T-shirt, and whatever sneakers he could find at the local sporting goods store. If his feet hurt, he bought better shoes; if he chafed, he applied a bit of petroleum jelly. His anatomy required very little in the way of specialized structural engineering to withstand the repetitive, high-impact motion of running. He could simply step out onto the pavement and let gravity do its worst, secure in the knowledge that his clothing would keep him reasonably comfortable.

For the rapidly growing cohort of women who wanted to join the running boom, however, the experience was vastly different. Women were entering the athletic arena in unprecedented numbers, eager to experience the same runner's high, the same sense of physical mastery, and the same health benefits that men were enjoying. They were inspired by the changing social tides of the feminist movement and the promise of a new era of physical empowerment. Yet, as soon as they took their first tentative double-time strides down the street, they ran headlong into a glaring, painful omission in the consumer marketplace.

The sporting goods industry, which had existed for decades to cater exclusively to men and boys, was completely unprepared for the female consumer. When women walked into local running shops or sporting goods stores in 1977, they were greeted by walls of black, blue, and grey merchandise designed by men, for men. There were no running shoes built on a female last; instead, women were forced to buy men’s shoes in smaller sizes, which were far too wide in the heel and caused agonizing blisters. There were no lightweight, moisture-wicking shorts cut to accommodate female hips.

But the most glaring, painful, and prohibitive absence of all was the complete lack of an athletic bra. The concept simply did not exist. The sporting goods industry had never considered the biomechanics of the female breast in motion, nor had they recognized that a woman might require a specialized piece of equipment to secure her chest while she ran. To the male executives who ran the major athletic brands of the era, sports gear meant bats, balls, helmets, and cleats. The idea of undergarments as athletic equipment was foreign, and the idea of discussing female anatomy in a business meeting was downright uncomfortable.

As a result, women who wanted to run were left entirely to their own devices, forced to improvise with whatever they could find in their underwear drawers. The lingerie industry of the mid-1970s was divided into two distinct, equally useless categories. On one hand, there were the delicate, unstructured, and highly aesthetic fashion bras of the post-sexual revolution era. These garments, often made of flimsy lace, sheer nylon, or thin cotton, were designed to look pretty under clothes or to disappear altogether. They offered virtually no structural support, possessed thin, elastic straps that stretched out at the slightest hint of movement, and were held together by tiny metal hooks that dug into the skin.

On the other hand, there were the heavy-duty, armored undergarments of the mid-century tradition—the girdles and stiff, wired bras designed to sculpt the female figure into a rigid, socially acceptable silhouette. These bras were built like suspension bridges, utilizing stiff, thick fabrics, heavy metal underwires, and complex arrays of hooks and eyes.

While these garments certainly held things in place, they were disastrously unsuited for any kind of athletic activity. The moment a woman began to run, the metal underwires would press painfully into her ribcage, the heavy canvas-like straps would cut deep grooves into her shoulders, and the rough, exposed seams and metal fasteners would rub against her sweating skin like sandpaper. Within a mile or two, many women found themselves bleeding from raw, painful chafing where the bra had rubbed their skin raw.

The physical consequences of this gear deficit were immediate and severe. Every step a runner takes subjects her body to forces up to three times her body weight. For a woman, this impact translates into a complex, three-dimensional figure-eight movement of the breasts. Without proper support, this repetitive bouncing causes significant strain on the delicate Cooper’s ligaments, the thin band of connective tissue responsible for supporting the breasts. Once these ligaments stretch, they do not snap back.

The result was not just long-term sagging, but immediate, acute physical pain. For many women, particularly those with larger breasts, the simple act of jogging was so physically painful that it was completely unsustainable. Every stride was an exercise in discomfort, a constant distraction from the mental and physical benefits they were supposed to be enjoying.

But the pain was not merely physical; it was also deeply psychological. In the 1970s, the sight of a woman running in public was still enough to turn heads and invite unwanted attention. Without a supportive bra, the visible bouncing of a woman’s chest as she jogged down a public street drew immediate, often harassing remarks from motorists, pedestrians, and onlookers.

The female body in motion was instantly sexualized, transforming a private pursuit of health and self-improvement into a public spectacle. For many women, the embarrassment and self-consciousness caused by this lack of support was more than enough to keep them indoors. The lack of proper gear effectively locked them out of the running boom, acting as a physical and social gatekeeper that whispered, in no uncertain terms, that the playing field was not meant for them.

This was the quiet crisis of the running boom. While magazine articles and television specials celebrated the democratic nature of the sport—proclaiming that anyone with a pair of shoes could be a runner—the reality was that half the population was being left behind, stymied by a few square inches of cotton, lace, and metal. The missing gear was not just a convenience; it was a fundamental barrier to entry.

As women continued to push past the societal boundaries of what their bodies were allowed to do, they found themselves literally held back by the very clothes they wore. The stage was set for a radical intervention, but in 1977, no one in the boardrooms of New York, Boston, or Portland was paying attention. The solution would have to come from the runners themselves.
