As mentioned in other reviews, these NB 996v3 tennis shoes run small. I have previously had several pairs of Asics Resolution 7s in a 10.5, medium width D, which are comfortable on first wear and have little to no break-in time. I had to go up a size 11, Wide 2E for these shoes to have equal room for my foot and toe box. And these soles feel a lot stiffer than the Resolutions, which makes me hesitant to play tennis in these shoes - they feel stiff just walking in them and look chunkier and wider than the Resolutions. I hope they get more comfortable as I break them.
