I ordered the blue wave drive 7's recently in 12 but had to send them back unfortunately, quite a bit bigger than I expected regrettably as they only had the 12's in on a decent sale.
Its baffling, I've been using size 12 energyforce xii for the past 18 months, (in my eyes the best shoe I've owned) which fitted perfectly, yet I've got a pair of size 12 energyforce iii that I just couldnt get used to,
Looks like I may end up going down the lezoline route
