I order Northwave because the sizes have always been consistant. Matched it to my size 45's they appeared two sizes too large. Matched to a friends 47.5 and they were the same size. Mismarked? Factory seconds? Though it works for me, with an insert, I'll keep them (or give to a friend), but I was really dissappointed.
