I have had these slippers for about a year now and recently bought another pair of the same fox ones as a gift. The headset itself feels lighter (not really in a good way. Top of foot is really beautiful and very comfortable. I ordered according to my standard American shoe size and the product was huge. This winter I could wear with socks! Weird half arch not in proper place but at beginning of heel, no arch where you should have one. Ive not tried the rear 3. Surprising, as my feet very rarely get cold. Except for these. I wore both of them so much that I wore out the rubber of the sole.
