I returned them but also bc they were blue! In fact the first time I wore them, which was for several hours, I forgot I was wearing brand new shoes. My favorite Keens shoe so far. This seems to have resolved the issue. I would appreciate if the seller can contact me. Ill update if it continues to disconnect. Ive had these over a year, waited to review to see if theyd hold up to constant use. Pros:- $75. I made sure she was keeping them in the included carrying case. The fit is perfect!
