If a piece of jewelry keeps its color and does not irritate the skin, I consider it a win. Bad lenses can cause eye strain, reflections and headache when you wear them for hours. Metal can feel more premium, but acetate can be more comfortable for long wear. Very thin fabric may be fine for summer but often looks cheap and becomes see through. Online shops that show detailed measurements and care instructions usually get my attention.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

I try to look for real photos of the insoles and soles, not only the outside of the shoe. That is why I sometimes leave comments myself when I test a new shop or product. Whenever I find something that actually works well, I tend to reorder it later. If the first order goes well, I slowly try more products from the same place.
Hope this helps someone.
