These are brand new, bike shoes never worn. SPD/Crank Brothers etc. compatible I think Pearl Izumi sizing runs a little bit smaller than most. This is from the MEC site description: Uppers are made of quick drying, breathable mesh and synthetic fabric. Low-cut construction for a light and fast feel. Nylon X-Alp ride and run plates provide great pedalling power when cycling, but are also comfortable to walk in when you're off the bike. Cushioned EVA run shoe midsoles provide off-the-bike comfort. Outsoles have carbon rubber lugs for superior traction. 2 forefoot straps and a ratcheting buckle to reduce pressure on your instep. Flexible forefoot and bevelled running shoe heel.
