As recently as the late 1980?s, professional road cyclists would wear a pair of socks over their shoes while racing and training. If asked why they did this, they would answer 'It?s warmer, more aerodynamic, keeps my shoes cleaner, looks better, and it makes me faster.' Of course, one could argue that putting cotton socks over cycling shoes makes none of those possible. DeFeet crafted a solution that actually keeps windchill off the feet, creates smoother lines, keeps dirt out, looks better, and ultimately makes riders faster. Slipstream?s? also last much longer than a pair of socks while barely costing more.
