isotoner Women's Classic Hoodback W Memory Foam Ash, 38.5/39 EU

Perfect size & very comfortable.

When you first put them on, it does seem like they are too small. No need to return them. Just get the size you're supposed to and wear them a couple of times and your feet will be able to creep all the way into the toebox and your heels will no longer come out over the back. These loosen up but not too much. Just right. VERY warm. VERY comfy.

Very comfortable and good quality. They do run small . Like 2 sizes off in my experience

I have Achilles Tendonitis + heel spurs so am hardly ever in the house without slippers! I’m definitely going to buy another pair in a different color. These have a solid rubber sole so they don’t slip and slide and the memory foam inside with arch support is like a hug for my feet. They are not heavy weight but feel solid and quality. I always require a little back lip on my slippers so they don’t fall off and these have that just perfect. The other pair I wear is very similar and sell for $60 a pair!!! They are a snug fit, but that’s how I like them and you can tell they will stretch and form in time. I love the gray because they don’t have the contrasting black sole.

The Isotoner Classic Clog was something that have 'fit the bill' for support & comfort. I normally wear isotonar slippers size M, 6.5-7. However this slipper fell short literally. The size was short and tight. A once ideal slipper brand, now questionable on fit. Try multiple sizes; buy a size larger and return what does not fit.
