Po-Zu's entire Vulcanised Sole collection is handed crafted in Sri Lanka and 100% vegan. The Vulcanised Sole collection features organic cotton uppers with a locally sourced Fair Trade Natural Rubber sole, certified by the Fair Rubber Association. Our Sri Lankan sneakers are ultra-comfortable, thanks to a 5mm memory-foam Foot-Mattress™ made with Natural Latex and Coconut Fibre.
