Our super-cozy slippers and boots come in a single size that fits most women's sizes from 6-10. (This roughly converts to men’s and youth sizes 4 - 8.5.) Our slippers and boots were designed to soothe aches and pains, keeping your feet toasty warm at bedtime or while chilling on the couch. To maximize comfort and softness, we have not added a sole intended for walking or venturing outside. In other words, slip them on, put your feet up, and relax! Shop Warmies footwear here.
