After years of wearing a smaller size of Isotoner ballet slippers with leather bottoms, I decided to try the terry ones to help my comfort level. Needed a little more toe room for conditions that happen to our feet as we age. While the XL 9.5-10.5 is technically too long for my foot (I wear a ladies 8.5-9M shoe), the comfort level from the larger toe box is worth the slight hang over in the heel sole area. For anyone struggling with hammer toe, bunions or hang nails, I'd suggest going up a size from your normal shoe. That being said, now about the quality. I have purchased other name brands and a few off brands in the past from Amazon and other retailers. You get little houseworn mileage out of others and they can't be washed for disintegrating. With Isotoner, you get quadruple the life! I have already washed my terry pair twice and they still look brand new! Always air dry (especially for the leather soled) but regular cool-warm wash in your machine and voila! Love these ballet slippers! They stay put to prevent falling, they are no skid and non-marking, they wear and wash well and the price can't be beat! Thanks Isotoner! This review is coming from a long time (25+ years) ballet slipper wearing Gal!
