There's the obvious wing height, tab height, etc., but at a glance, they look very similar. Had they got the toe box like the recent flight '89s, the shape would have been apparent to even the untrained eye and so fire. Missing that toe box improvement is a damn shame. When I look at my WC4 and BC3, the NA looks so damn amazing; when I look at these, I tilt my head and raise my eyebrow....just looks off. No designer I've ever worked with would be OK with this going to production. I honestly think something went wrong in the product development/production process; no way they designed it to look like this!
I'm sure once I get these on feet I'll just be happy to have them, and not think about it so much, but right at release while I got my inspector gadget brain on, I have to say that these disappoint somewhat. Unlike the infrared 6, which the moment I saw them and tried them on, I was like, damn, these are so much better than my '14s.
Gotta get them home to compare, but the boxes on these 10.5s seem small. Maybe from being from Europe, they used a size 8 box or something? I think I read previously that the box size changes at a given size. Anyway....
