Customer Reviews

Comments: Wore the Mudclaw 300 to Tough Mudder in Seattle this past weekend and am extremely happy with them. The terrain was 90% off road and the Inov8 Mudclaws worked like a champ. Ascending and descending loose dirt and mud covered hills was a piece of cake even as I had people slipping and sliding all over the place right beside me. It took a couple weeks to stretch the shoes to a comfortable point. In my case, a wider toe box, but it is possible and worth the money. My Mudclaws are not a nice yellow color anymore, but they will be the only shoe I use for future Tough Mudders. One word to describe them, "Impressive!" Next stop, TM in Vegas.
