Well, they only squeak on clean floors. Fits comfortable, true to size, in the sense they are comparable to other manufacture's sizes. Used on the trail, around the house, and on city streets. I was a bit disappointed when the shoe slipped, and I was expecting more "bite" on a rock. If you concentrate on foot placement, no problem. But if you're casually about foot placement on the rock, they will slip. A lot more than expected for
the sticky soles they advertised. My biggest complaint is they lasted only 3 months before the rand started to come apart. Shoes should last much longer and not require the customer to glue the shoe. I believe, if you flex the shoe a lot, like on approaches, the rand will delaminate. Even not wearing the shoe you see the delamination in process. Majorly disappointed.
5.10 should add a tube of glue to each box.
