Review on 3-Piece Dr. Foot Toe Tubes: Soft Fabric Sleeves With Gel Lining To Protect Toes From Corns, Calluses, Blisters, Bunions, Soreness, And Hammertoes - Medium Size Gel Toe Separators For Optimal Relief by Gloria Jones

This is a very useful product. However, if it doesn't match the exact diameter you need then it may not be quite as helpful. My podiatrist was happy when he saw a piece of this on a toe that had been operated on. The issue I have is that the it could fit about right but still not be comfortable due to a slight extra squeeze from the material. For me a very slightly larger diameter would better but I see the 0.8 as the largest. I am dealing with a short toe and it is (the toe), of course, not a manufactured thing with a fixed diameter. In any case it is worth a try if it seems to be about the size you require.
