Overall, I am very satisfied with the quality and value of these flip flops. I run 55-60 miles a week and need a sturdy, durable, comfortable shoe - Brooks is it for me. At some point when my patience is a little more abundant, I?ll try pairing them to my iPads, MacBook Air and Mac Mini, not today though. Also some sellers incorrectly name the shoes so youll have two different shoes with the same name "Kadee" but clearly different shoes. - The letter on the inside on insole are gonna rub off pretty soon maybe one wear. not only do you have to pay for it to begin with but then they charge you AGAIN if returning. Inconsistent size. POSA -An open-end wrench to hold the supplied lock nuts (I used a 10mm because thats what I had, 10mm was slightly too big. The 1 Step Pairing was instantaneous.
