These adjustable slippers turned out to be the perfect solution to my ’special need’. I have lymphedema in one leg/foot only. It has been years since I have been able to wear a traditional pair of shoes or slippers. I was able to leave the left slipper adjustment "out of the box", and the right slipper adjusted enough so that I was able to buy just one pair of slippers rather than two of different sizes. The slipper was also able to adapt to the added thickness of my foot that the lymphedema causes. Great product, and I will be back for more!
