I have several pairs of Propet shoes. They usually help me stand up and support my back. I bought these specifically for my carpentry shop and I was a bit disappointed in some of the features. The lacing system is weak and in fact one of the shoes has already snapped (occasionally, not daily, for the first month of wearing). Also, there seems to be a hump on the sole of the left boot (which I don't feel on any other boot, so I concluded it was this boot).
