With unprecedented traction and grip across all surfaces (including slippery ones), the multi-directional lugs let you brake and change direction with control.

The Pro5 Puncture Resistant finish is a lightweight and flexible 0.8mm layer on the sole. Protective underfoot to keep painful bits out, but still letting all the feeling in.
