These women's barefoot water shoes combine barefoot-style feel with protective performance for gym training and summer outdoor activities. The ultra-thin 4mm 0-drop sole encourages a natural gait to help reduce discomfort in knees, hips, back, ankles and feet while still providing dependable protection. Designed with a wide toe box to allow natural toe spacing, the shoes help improve balance and foot strength. Uppers are available in breathable knit or polyester to keep feet cool and relieve joint pressure. The insole is rubber and the outsole is a slip-resistant rubber composition (TPE, TPR, etc.), giving traction on wet surfaces. Sizes are offered with men/women conversions (examples include 3.5M/5.5W through 9M/11W) and colors available include Blue, White, Black and Pink. Recommended by certified podiatrists at the Phoenix Foot & Ankle Institute for stability and comfort, these lightweight shoes are suited for everyday wear, aqua activities and training sessions.
