I rode them through 9 miles of steep dirt with brutal climbs and descents. While others slipped and fell everywhere, I held on to everything. Good in mud and water. The right leg was a bit narrow for some reason, but other than that it didn't affect my performance. They have proven themselves, hence the 5 stars. We highly recommend wearing or running in them at least a week before each competition to wear them. If you're into Mudder, I recommend grabbing MudGear compression socks. Have fun there!
