With the comfort you've come to expect, the nylon strap Chaco Flip Thong for women features a certified pedorthist contoured BioCentric footbed provides exceptional support and shock absorption that is super light and flexible. A new generation far beyond the "thongs" you grew up wearing, slip on functionality cradles every contour of your foot and features a broad heel cup that accommodates a variety of widths. Barely knowing when you have them on, the polyurethane construction gives non-compressible long life, while an EcoTread Vibram outsole, made from 29% recycled rubber, is environment friendly. All terrain traction gives new meaning when negotiating tricky forest terrain or the summer beach rental.
