The shoes are very comfortable and supportive. They are well made and very comfy. But the shoes appear to be brand new and unworn. This is a great shoe.

I prefer leather for sturdiness and it's breathable. Always wear 623’s to play tennis.

I have some feet issues (bunions) and nb gives me great support. The toe box offers enough room to wiggle my toes, even though it has a tapering toe shape. Nb normally is a bit more roomy than competitors in toe box.

The seams are serrated and not covered by material or foam. There is a manufacturer's defect, which they do not have a replacement for. I can spend more money just to get an insole that doesn't fit my shoe. These are clearly counterfeits!
