Have done rack pulls at 350 without it bolted just to see. I tried putting a thin layer of hot glue over that inside part of the shoe that my heel touches and didn’t seem to have any issues while wearing them around the house. Up close you can tell its not a good nor sturdy product. I ordered white and they are stunning, super comfortable and cute! Most games have horrible settings that dont feel normal to a real car driver. I have slightly chunky feet and my pinky’s poke out the side. Clearly other reviewers didn’t read the instructions. *Also for you Samsung Galaxy phone owners, do an adapt sound test to do a "sound test" to see what frequencies you are able to hear. I have yet to find headphones that I can wear for more than an hour without having to take a break. The anti sway bracket was broken in two when I opened the box.
