"Polyester webbing ‘Z Straps’ with adjustable buckle. EVA construction . LUVSEAT’ arch-support . True sizing . Chaco’s Chillos Slide are a set of ultra-relaxed sandals. They’re made from that EVA stuff, which means they’ll float on water, which means they’re bang-on for long days spent suppin’ cervezas poolside without fear of losing them to the deep end. They’re also equipped with Chaco’s world-famous ‘Z Straps’ too. Customisable comfort never looked so good.
