Have had Keen's for 20 years and love this brand. I ordered these slip ons to replace a worn pair and they were the wrong size for previous Keen models. They were uncomfortably tight and seemed smaller than usual. Also, the signature wide toe box is noticeably less wide and looks like any other brand. They also stained my socks. As for the seller, I think this is the first time I've had to pay for return shipping and the 10% restocking fee with Revain. Buyer Warning. Read all the fine print. I will not buy from this seller again.
