They could just be too narrow for your foot. Imho you should be looking to have 1/2" between your big toe and the front of the toe box when your heel is snug to the back of the shoe. If the width is too tight with the 1/2" you need to keep looking. Maybe look at the booze Vulc if you're set on adidas because it is a little wider in the mid foot and doesn't have an arch the way the Suciu and ADV shoes do. Yes, it's not as cushioned as the Suciu and wears out faster, but you can swap the insoles and a proper fitting shoe is worth whatever it costs.
Not even close lol. The 9 1/2's fit slightly snug when I first put them on but it was a world a difference.
I tried them on with no insole for the hell of it and they felt like fucking boats! Then I tried them with my lunarlon insoles from my CTAS's and when I walked around the heel slipped up and down. Then I put back in the Adidas insole and they felt like heaven even if ONLY SLIGHLY snug. I have a feeling that once these break in they will be my new favorite shoe. Love the shape, the comfort, and the fact that feel a lot slimmer/less bulky than they actually are.
So unless you are 100% sure you're going to use non stock insoles DO NOT listen to anyone who says 1/2 down on these babies. And if you're like me and are between sizes depending on the shoe, get these in the bigger of the two sizes for sure.
