System engineered for a seamless interface with SHIMANO S-PHYRE RC901 and XC901 footwear. The S-PHYRE Toe Shoe Cover features an adjustment port that perfectly matches the Boa dial on S-PHYRE footwear for instant, on-the-fly adjustment. These versatile toe covers deliver cold weather protection and packability during changing weather conditions.
These fits so well over the S-phyre shoes. It isn't a struggle to put on over the Shimano cleats. The bottom fabric feels really durable. The top isn't a super thick insulated shoe cover like some other neoprene covers but does the job of blocking wind and giving a little bit of extra warmth on colder days and cool morning rides. Haven't ridden in any wet conditions with them yet so I can't comment on any protection there. The color is a grey/metallic color vs. black. So it would be nice if they would be black in color. But for their function, I love them.
