I finally got around to using these and they worked better than I thought they would!!! I have one pair of cowgirl boots that fit me fine if I could get my foot into them but it was so difficult to do, that I would give up or run out of time to keep trying! I have several pairs of boots but this one pair were the only ones that caused a problem. I finally decided to try the boot slips a try when I wasn't in a hurry, expecting it might not go well!  Needless to say, I had my boots on in plenty of time because my feet slipped right into my boots, I broke away the boot slip, pulled them out and I was ready to go! I can't believe I didn't try these sooner!! I had called around to see about getting said boots, stretched but thankfully, I tried the boot slip first!  No more strained muscles from the struggle!!!
