Pros: Shape ups are super comfortable to stand in all day. I work on a bar without rubber mats. Tile on concrete - small space, slippery when wet, sticky when dry, and these help my posture yes. I have a lot less back pain and foot pain - even if i work a double. they're better than danskos.

Cons: The strap is not flexible - the velcro portion is tiny. Lean forward and the velcro comes undone and you walk right out of your shoes. so glue them in place and then slide your foot in and destroy the back part of the shoe. I had to buy a lace up pair after demolishing these at work.
