I have been using the ECCO men's classics for than 10years. Though pricey, its always a very good investment. It fits snuggily and yet not with an iota of discomfort. I would usually use a size 13 sneakers, but i find the 12/12.5 in the ECCO Classic Moccasin fits just right. Unfortunately, i am no longer able to buy this particular model. It seems to have been replaced by the Moc 2
