Sneaker technology has advanced far beyond the days of stone-chiseled soles, wheat-woven heals, and steam-powered shoelaces. Step into the future with today's Groupon: for $35, you get $80 toward athletic shoes from Spira Footwear's online store. Groupon purchasers receive free delivery.
Defined by the patented, lifetime guaranteed WaveSpring, a compact mechanical cushioning system that reduces ground impact forces by 20% so wearers can saunter longer, Spira cobbles specialized athletic shoes for all walks and sprints of life. This energy-recycling technology is ideal for committed athletes and has been used in numerous race victories such as the Dallas White Rock Marathon, with running shoes for male and female marathonistas, comfy kicks for men and women power-walkers, and high-tech slippers for 100-meter channel surfers. The hornet-hued Stinger ($105), available in limited, select sizes and set to return in an updated model later this year, is an elite unisex road-runner designed specifically to maximize performance and reduce fatigue. Spira also carries the popular, high-mileage Odyssey ($114.95), as well as the sober black WaveWalker ($94.95), replete with cutting-edge cushions and eschewing speed for comfort. Watch the closeout page for retiring favorites, such as the men's Volare 3 ($79.95), or the Mesa ($89.95), a sleek slip-on for women that, like all of Spira's footsheaths, simulates air-walking without the need for bulky hovershoes.
