When I first tried on the EMU Australia Women's Jolie Slipper, I thought it was a bit tight (especially after wearing my very stretched old slippers). I had bought them in my normal shoe size although I planned to wear these slippers with gym socks. But I'm very glad I did not get a larger size because within no more than two days, the slippers fit perfectly even with my gym socks on. They had stretched and adjusted to the contours of my feet and now felt very comfortable: a larger size would have become too big and loose. These slippers have kept my feet warm and cozy in an apartment which gets a lot of cold air drafts coming in from various places along the floor. The slippers are quality workmanship: well made with thick rubber soles, tan sheepskin suede upper and thick wooley interior. Extremely happy with my purchase.
