Cycling shoes feature a high-density breathable nano synthetic upper and wear-resistant nylon sole. Textile inner, made of nylon and TPU, featuring a tooth design for a strong grip. Suitable for mountain bikes, road bikes, indoor cycling classes. Compatible with Look Delta or SPD clips (I can provide both). Non-slip soles are lightweight and breathable. Perforated design in upper material super breathable, keeps the feet dry, and not slippery. Gear technology for quick tightening of laces with the coil button lacing system. Color: Gray Camo. Not sized like traditional cycling shoes - more TTS. These are an EU 40 or US 9/9.5. I'm a narrow 9.5/10 and they fit like a glove so listing as 9.5. EUC: bought new + only worn a few times at Soulcycle before deciding on another style shoe. I've owned every cycling shoe brand around - Shimano, Soulcycle, Fizik, Nike, etc. and these feel no different! No stains or damages, thoroughly cleaned, smoke-free home.
