Hate to be that guy to curb teh bantz, but something about the shape of that at the back suggests maybe medical scarring? Did Landon have a tumor removed or something?
I have had a similar experience going back to an old pair of Vapor 13s after having given them an 18-mo break. It's like they were a whole different boot, whether the material has settled and worn out or my foot has changed shape, etc.
Got the longsleeve Germany home, a longsleeve Argentina home, and a short sleeve Spain away. Might try for the purple England one if it ever gets back in stock anywhere.
Germany home is incredible.
Which is not necessarily a bad thing. The Crazyfast+--if it works for your foot--is a fantastic boot (and I would personally favor it over the Vapor15)
