This is my second pair of Acorn slippers, my other pair being an enclosed foot style more suitable for cool weather. Being an "Elder", I wanted something cooler for the hot summer yet soft on the bottom of my "older" feet. They are "soft" but unfortunately also "hot". Wearing them you feel as if you are walking on THICK sponges with almost no tactile sensation with the floor thus making it hard to maintain your balance. The memory foam is also a bad choice as it reinforces any improper step caused by weak ankles. And, the size runs large and wide. I weer a size 8D in athletic shoes, yet the Acorn 8-9 (another bad idea by Acorn) is so large and wide that I have to cramp my foot to keep the slippers on. The product does get one star as I like the summery plaid design. This is the first product I've bought where I intend to throw them out after only 30 minutes of wear. PLEASE DON'T BUY FOR ELDERLY PEOPLE!
