Thank goodness for fast shipping, they arrived on time. Weve owned for several months and have only charged once. ??The free giftcard offer in the box is a scam! Heres my advice: if you are reading reviews on size you are probably trying to decide between 2 sizes. It would seem that the Onyx ramps up and plateaus faster. I wanted to get some lounge wear that was a little more stylish than crappy sweats and ancient t-shirts. Of course like any shoe it needs to be broke in. Very nicely built. I was sold on this product as they claim that it?s durable plastic does not crack, however I was surprised to see that when I begin putting together the boxes together that 2/3 were cracked! I like the support and the feel.
