I have the grey 'Friends of mine' dog slipper and I think they run true to size - I am usually a UK size 6 (Euro 39) with a tiny bit of space in most shoes, and these MJ shoes fit me with a tiny bit of room (not enough to slip up).
I am contemplating getting them in red too - they are so cute and very comfortable!
Thanks so much for the reply. I just got a pair. They are the cutest shoes I've ever owned, even cuter than the CO kitty flats. Also, I got a good deal on it! Yayyy!!
P.S. They are amazingly comfortable due to the cushioned insole.
Ooh, what colour did you get? I am toying with the idea of getting a red or cream pair...
I agree with the comfort part completely - outside of how good they look, the first thing I said to my boyfriend when I put them on was how shocked I was at how comfy they were. I took them to Florida with me last year and wore them to theme parks etc as I could do a full day of walking in them with no pain
I got the light blue one However, regardless of how cute they look, they did get dirty easily. So maybe it's a better idea to get a darker shade. I guess the red will look better and newer than the cream in a long run.
