These are basic but they do work. I think they are more difficult to get on and off. I don’t like that stick up high. I have them but really don’t use them any longer.
I love these. They look great and I replace Etsy ones that I had on rack originally. They can slide off if on front and you have really tight j-cups for instance but overall they work well for me.
This works well for the money. It has good grip and plenty of room for your feet. I use this with my smith machine and it works great for doing calf raises.
