Example Input: I bought a pair of Harley-Davidson brand boots several years ago, but they were always a little too narrow and uncomfortable to wear for long periods of time. I was about to toss them into the Goodwill bin when I thought of shoe stretchers. After reading a number of reviews for various brands and types, I bought these. I followed the directions and now my boots fit perfectly. I recommend giving these stretchers a try before getting rid of $100+ leather boots or shoes that are too tight. Just be patient and follow the included instructions. I also appreciate the inclusion of a long shoehorn, all packaged in a convenient bag.
