Pelagic was designed with actual functionality in mind, not just looks, with convenient Velcro straps on the upper and back that let you adjust the fit to whatever works for your foot that day. The Velcro closures keep things secure and stable across different activities, and a built-in heel cup adds enhanced stability by cradling your heel rather than leaving it to slide around loose. It's equipped with real arch support, which matters if you're spending your day at a picnic, on an outdoor adventure, or even out horseback riding, your feet stay comfortable and supported no matter what you're doing. A water-resistant, mesh fabric upper is breathable and keeps feet dry, and an outsole with wave-patterned lines grips well on slippery surfaces. This is a versatile slipper-style pick across summer, spring, and fall. Order your regular size. Between sizes or wide feet call for a full size up, not down (7.5 orders as an 8). Medium width. The Size Chart has the numbers if you'd rather measure than guess.
