Unlike traditional wellington boots, the WedgeWelly offers a snug and supportive fit. Loose fitting boots can lead to flattened arches, resulting in injuries to your feet, ankles, knees, hips and back. WedgeWelly became famous following it's successful pitch on the hit TV show Dragons' Den. Theo Paphitis invested in the company and now owns 25%. Theo Paphitis says 'The WedgeWelly is a very exciting product, it's been designed to be both practical and stylish'. WedgeWelly boots are constructed from rubber compounds, and are 100% waterproof.
