Very cool looking shoes, interesting material, nice quality. The sizing is consistent with other Adidas i have. Fit might be a bit on the narrow side, but that kinda comes with this style. Comfort I found to be lacking, nothing to do with the fit, literally the footbed padding is quite firm / stiff. I have other low profile "driving shoe" style shoes that are much more comfortable as a casual shoe. Maybe if used as an actual racing shoe, it'd be more approrpriate?

These are quite comfortable but be aware of the narrow toe box. Recommend getting a bit larger size for wider feet.
