The 5.5 mm FeelTrue outsole on the Genesis Sandal comes pre-laced with stretchy, tubular cords that encompass your entire foot and attaches to the ultra-soft toe peg. A nylon Achilles strap sports a silicone grip to hold your foot securely and comfortably in place and eliminates annoying slapping sounds that flip-flops make with every step. The rubber outsole is slightly contoured around the heel and can be trimmed with a pair of scissors to flawlessly match your foot shape. Subtle treads provide traction without interfering with the barefoot feel. The Genesis Sandal is a unisex style—a men’s size 7 is the same as a women’s 8. It fits true to size and a snug fit is recommended.
