Glerups Women's US 8 (EU 38) Slip-On With Leather Sole Light Grey. Felt slipper, 100% pure natural wool with soft calfskin leather sole. It keeps the foot warm and dry, due to the wool’s great capacity of absorbing moisture. These are the best, simplest, most thoughtfully designed slipper. Unisex size, see chart for details: US W 8, US M 6.5, EU 38. I wore these inside with socks for 3-4 days, so the soles are a bit dirty. Otherwise, the shoes are in excellent condition.
