Adds just enough cushion to your steps when walking on all the concrete surfaces we seem to have now at work and some people have concrete slabs they live on. Im a repeat customer for the exact same pair, even though I looked at other brands/models for my replacement pair so that should tell you something. A hair bit loose but I can live with that. Theyre also beautiful! A little bit hard to assemble. There is only marginal improvement in situational awareness in my case. Shipping & Item condition:Arrived on time and in good working condition with no damaging. Nothing wrong with using the straight edge, but actually bought the bars because of the angled option. However, the instructions were entirely in Chinese. I tried various methods of lacing them and spent a week around the house trying to "break them in" but never found anything that worked and just couldnt tolerate the foot pain they caused.
