I've never been a big fan of slippers, they have poor grip and are generally poorly finished. I gave it a go and so far I'm very happy. Fits more like shoes (my size is 12M and they fit perfectly) without arch support of course. Cut-outs on the sides make them easy for this old man to put on and take off, and they don't feel like they're about to fall off. Just the right amount of insulation that feels like a higher quality faux fleece, not too thick but warm. Good upper construction, wide toe box, good material and a decent rubber outsole for getting onto the porch or driveway quickly. good price too. Very satisfied.
