Dry and comfortable is where the SMX-5 waterproof boot fits in to the lineup. Street and race boots tend to be less comfortable, not here. Purposely built to increase comfort, the heel has an achilles flex zone to increase comfort and foot entry. Protection is standard by having PU covering over the heel, toe and shin area to absorb impact. Lace up the quick drying polyamide liner and boot to get a custom fit and comfort without having the damp feeling from the previous days ride in the SMX-5 waterproof.
