Wasn't sure about these but decided to try them, thinking I could return them if they weren't right. Slipped them on when they arrived & haven't wanted to take them off since. They look good, are so comfy & a pleasure to walk in. Not heavy or clumpy. It's been pretty chilly the past few days, but these have kept my feet lovely & warm without sweating. Have just ordered another pair in a different colour & can't wait for them to arrive. I always order a size larger in crocs than I usually wear in other shoes, so be warned. A 5=6. Highly recommend them for warm winter feet.
