The Giro Men's Republic R Knit Road Cycling Shoes have an internal TPU skeletal system provides support where you need it, while the knit offers suppleness for superior sock-like comfort. The upper is DWR-treated for water repellency and easy cleaning, and a rubber toe guard and bonded TPU heel increase durability and abrasion resistance. A new nylon and rubber co-molded outsole provides improved durability and better traction for stable footing on roads, sidewalks and gravel when you're off the bike.
