old shoes? You feel comfortable putting together a reservation with them. Initially they fitted perfectly, they were snug around my feet but after just one use with thicker socks the skin of my shoes stretched and now when I wear thinner socks with them they are too loose, absolutely my fault for doing it Don't take W Gabs' advice, double the size for a consistent, snug fit. I was too short sighted great work W Gab I will listen next time lol. I notice that I wear thicker and thicker socks with my new brown leisure slippers. Hope this helps others. Many Thanks
