Keen Chandler CNX Shoes keep your feet cool and comfortable, even when the sun is out and your folks have you out for a weekend camping trip. Keens CNX technology provides lightweight protection and a natural fit while using the bare minimum of upper materials to keep the weight and temperature down. The breathable mesh uppers and linings allow air to flow freely through the shoes to keep your feet cool and comfortable. Keens lace capture system and contoured arches provide a secure fit and plenty of support. The finishing touch, the non-marking, multi-directional traction outsoles, provide lots of traction outside without marking up the floor inside.size youth 4
