I have ordered a pair of "Old Friend" mocs/slippers every year and a half or so for years...this is my 4th pair.  Always warm and comfortable and then the seams break out along the sole and you need another pair but that's OK for the price.  I will say that this version has a heftier sole than prior ones I've gotten and are more suitable outside than prior pairs...and the fit seemed a little snugger but they stretch quickly but they definitely seem a little shorter than the prior (or just different?) models I had had before.  I wear an 8.5 shoe and have always ordered 9s which were roomy at the toe...these seem a little shorter...I almost returned them but after wearing they seem OK...If they had half sizes I might want a 9.5.
