Overall these are great shoes, the latest version of the ones I've been buying for years. HOWEVER, the language is too short, much shorter than in previous versions. The upper lace—the heel closure—slips off the tongue after 50 strides and digs into the ankle for the rest of the day. I can't skip this lace up because, as the name suggests, my heel slips off when I do. (I would have sent them back but it's been too long.) Very disappointed, my favorite shoe for ten years.
