Made the mistake of going barefoot at home on hard floors for years & now paying the price with a flattened arch and foot pain. Own a pair of Vionic sandals that I love for their outstanding arch support and on a whim, thought I’d see if Amazon carried Vionic. Found these wonderful Vionic house shoe/slippers and couldn’t be happier! They fit (wear a 6 1/2 in most shoes) true to size, are soft but firm, and feel great, never taking them off. At first, thought I may have bought a half size too large cause they slipped a bit at the heel, but after wearing for a while they molded to my feet quite nicely & I wouldn’t change a thing. They’re very cozy and warm inside but not hot. (I don’t wear w/socks) Also appreciate the sole doesn’t have a deep pattern/groove on bottom that imprints ugly tracks when walking across rugs or carpeting, these are subtle. They delivered quickly in one day and arrived perfectly packaged. Would definitely buy again!
