Defeet Slipstream Refelctive Stripe 4"Overshoes AW20 - Hi-Vis Yellow - S/M}, Hi-Vis Yellow
  • £25.19
  • RRP £27.99
  • Saving you £10

DeFeet Slipstream Reflective Stripe 4" OvershoesThe DeFeet Slipstream Reflective Stripe 4" Overshoes keep a cool wind at bay, prevent your best road shoes from getting covered in dirt and also boost your profile on the road when light levels are low. As recently as the late 1980s, professional road cyclists would wear a pair of socks over their shoes while racing and training. Why did they do this? They would answer "It’s warmer, more aerodynamic, keeps my best shoes cleaner and looks better". Of course, one could argue that putting cotton socks over cycling shoes makes none of those possible. DeFeet crafted a solution that 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. And with the Reflective Stripe 4" Overshoes you'll be more noticeable on the road too.PLEASE NOTE- A small hole is required to be cut for your shoe cleat- NOT waterproof, these overshoes are designed to reduce windchill- Low temperature wash only- Not suitable for tumble dryer use- This item comes as a pairFeatures:Material: 94% Nylon, 6% LycraThe original DeFeet shoe cover designed to be worn over road cycling shoes with cleat systemsKeeps windchill off feet and dirt off shoesFeatures a knit-in cleat guide to cut your own openingThree season product; cool to cold, damp to dry conditionsReflective detailingMachine wash cool, tumble dry low or hang dry.
