New on the flip-flop scene, the North Face 3-Point Optimus Boa features a built-in device to achieve the perfect fit. Differing from the strappy, too-fussy alternatives for securing sandals, the 3-Point Optimus maintains the flip-flop shape but uses the patented form fitting Boa system to adjust to the contours of your foot. Turning the wheel moves stainless steel cables located inside each strap, which ratchet around your foot for a snug fit. Whether for running around a city or down a stream, this flip-flop will stay put. Though it's not really an option for the fashion-conscious, the Optimus is both land and water compatible, featuring an antimicrobial footbed and high-traction outsole.
Available at Backcountry for $75
