I agree with other reviews that you need to go up a size. Normally size 4, I find that the size 5 in these slippers are a very neat fit. They are also quite narrow so wouldn't be suitable for a wider foot. They are so light you hardly realise you are wearing them, and feel lovely and warm. Wouldn't have wanted to pay the full price, but taking the black ones at the reduced price was a bargain. Just hope they last a long time!
