First, I FINALLY really love these shoes/slippers.  The problem is that it took trying three pairs to find ones that almost fit!

I own two other shoes made by Simple, and they're both about 1 1/2 years old.  They fit PERFECTLY, which is great because my feet are slightly narrow, and they're size 11M's.  This makes sense because I almost always wear size 11.

So, I ordered a size 11M pair of these, and, while they were a little short for my right big toe, what was worse was that they were WAY too narrow, feeling almost as if I had a compression wrap over the top-front of my foot.  VERY uncomfortable.  I returned those and ordered an 11.5M.

These turned out to be even shorter than the 11's (!!!), but they were somewhat wider.  Those went back too, and I ordered a size 12M.  They fit much better, but they're actually a little loose, more in the area of width than length.

They are extremely comfortable, and all 3 pairs I saw were VERY well made and look as durable as the other Simples I've owned.  My advice, though, would be to order a FULL size larger than you usually wear, and, hopefully they'll fit.

I appreciate and applaud Amazon's paying for shipping both ways on all of these, but I expect their price will have to go up soon because, as I calculate it, with their paying shipping 5 ways, they couldn't have grossed more than a dollar on these.  They could save themselves some money by posting to order a full size larger, as many other reviewers have noted.

Great shoes, great price, and great service from Amazon -- my best wishes to you on receiving ones that fit!
