Spidi X-Trail OutDry Boots The Sidi X-Trail OutDry Boots use abrasion resistant micro fiber for a shell more consistent than most leather. A waterproof membrane keeps out rain and wind while still allowing your feet to breathe. Inner mesh lining helps wick moisture away with a vented plantar to keep your feet from getting too sweaty. Reinforcement at the ankles, toes and heels provide protection against common motorcycle injuries.
