Thank you for viewing. These are sabot sandals with adjustable spindles. The upper material is water-repellent, preventing water penetration. The insole uses very warm brushed material and has low-rebound, comfortable cushioning. The sole is a non-slip synthetic sole. They are well-made, but there may be some imperfections in the finish.
