I actually got these for my mother who loves to wear knee-high boots but calf trouble finding some that are her size to accommodate the size of her account, and I think these are going to be absolutely perfect for her. While my calves are a little large I thought that I would put these on just to get a feel for them before I gave them to her knowing that about an inch of space extra in the calf area was all that was really needed, but when I tried them on there is about two to three inches of extra calf space which is great but I wish there was a way to adjust it for a tighter fit if you have a wide calf but not necessarily an extra wide calf.
I feel like I could wear these with two pairs of fluffy knitted leg warmers bunched inside and I would still have extra room.
