I love these bands. They are a great; flexible, and strong rubber. i slip them easily over my sneakers. I started with the Yellow, which is marked Easy. Then i recently went to Blue, marked Medium. I had to concentrate on controlling my stretch. The last, color Yellow, is marked Hard. I have not even taken it out of its cellophane sleeve. Obviously they are fresh and have not been sitting on a shelf in some warehouse. The price which includes shipping is fair. I thought the gold envelope was a bit over the top!
