My feet feel secure in the slipper and yet there is some cushion and thats to the good. In other words, most of the bottles will be either too big or too small for it. This is something I think the smaller stands without the same kind of wheel support would feel tippy doing or simply have your tire fall off of the stand. "Cloud cushion" is accurate with these shoes, which is shocking for the low price point. Assembly was easy enough, though the bike wobbled and felt "light". Theyre based on the US (huge deal to me) and were easy to reach by phone and email. Small and comfy to use, good movement vs screen reaction. I picked these up to use in my office for music and conference calls. Soft padded footbed and a nice rubberized (but soft) bottom so you can run outside if necessary. This spice rack is extremely attractive, well designed and precise with every detail, including directions which made assembly a breeze I could not be happier with a product and it was so nice to feel not ripped off by an overpriced inferior product, which happens quite a bit when you shop online.
