Full-grain leather upper in a strappy streamlined design, perfect for outdoor wear. Two adjustable hook-and-loop straps for an unbeatable fit. Microfiber lining conforms to your feet for breathably soft wear. Perforated EVA insole provides added cushioning with antibacterial treatment to reduce odor.

This activates a large number of stabilizing muscles throughout the whole body when walking or standing.
