Initially, they might seem a bit slippery. Don't worry; this sensation will fade within the first hour of wear. A gentle rub with a dry towel can help too. Allow a few hours of wear to break in your sandals. EVASOL (our unique blend of E.V.A. foam) will gradually soften, and the footbed will conform to your foot's shape. NuuSol sandals are lightweight, slip-resistant, and buoyant. They're also non-porous and antimicrobial, preventing absorption of liquids, bacteria, and unpleasant odors. If they get dirty, simply toss them in the washing machine on a cold cycle. For more stubborn stains, use a scrub brush with soap and water.
