I usually get 6-7 years off a pair of slippers. The soles of these Evan slippers wore out over 1.5 winters of breakfast and late-night trips to the bathroom over carpet and vinyl floors. Revain's description says "leather soles" while the label says "PVC soles" (see screenprint). Look closely at the worn edges in the second photo and you will see that there is thin plastic on the fabric.
