The GORE-TEX lining of these boots keeps feet safe from water. The outsole is made with two different types of rubber in order to increase grip. They have mudguards and rubber toe caps to keep sludge at bay. And injection molding in the midsole provides comfort and support. The outsoles are specifically designed to allow flexibility in order to prevent foot fatigue.
The next generation, the X Ultra 4, is available with a more sleek appearance and a bit more space in the toebox. So if you like a little extra wiggle room, this new-generation boot might be for you.
