Two pairs of washable Striper IIs (navy and grey) have been added to the collection and they are the best of their kind. While they haven't used their 'machine washable' ability, they clean up brilliantly with a wet towel! Leather-like material, soft and comfortable, easy to clean but not waterproof. Check out the "Storm" variant of these shoes, which also offers a high-top version. I love these shoes! There are so many options in the Striper II series alone that it's difficult to pick a favourite. That's probably why I have 15 pairs.
