It?s very sturdy and great for all shoes, except for stiletto heels. Plus the upper straps are adjustable. This keeps them all together and I never forget! They have been working out great for her. I will say for me they ran big. Works great with Power Beats Pro. They are warm and soft and perfect for wearing around the house. i did try the sam edelman 1 strap, it was beautiful but not comfortable to walk in. I could see how some people may like these, but not me. These are not your traditional "seed bead" size - theyre bigger.
