We've designed our Florentia Rain Boots with all the stylish and functional features you've been looking for! Our super comfy,  eco-friendly rain boots are made with Yulex® natural rubber, the world's first plant-based replacement for neoprene. Yulex material is waterproof, biodegradable, plant-based, renewable, and stretchy enough to accommodate extra wide calf sizes up to 19".  The 2" block heel and platform toe add a dash of panache as you comfortably traipse around town looking your best while staying dry.
