I carry luggage and a spare tire when traveling long distance, sometimes over 2,000 km. So in comes the sliding sock, I was afraid it would make me slide to much (my 14yo son and his friends were waiting to laugh at me when I fell lol) but it didnt, it was perfect. They fit a bit tighter than expected. I hike enough that I would dish out the money on a pair of Chacos again if they were the right shoes. The heel pad is not adjustable but does have a small amount of stretch at each end. I ordered this product once, and it came with 1 bolt and 1 nut out of the 12 of each required food assembly. I use this product only on dresses with no stains, so you may have to use a dry cleaners for heavy stains. ??I wear a size 9 shoe. Honestly, I went out on a limb ordering these boots. So I finally realized it is because for the first time instead of womens, I bought unisex.
