I installed them to work on the TV in the den, but let say I decide I want to watch TV in the bedroom. Im concerned about the strap, as it is not adjustable and after a few hours of wear, then it does get a bit noticeable. One issue though, and it could annoy a few users at first. Biggest draw back for me is that if my phone alerts it cuts off audio and doesnt come back. 5 in every type of shoe. I bought size 4 for my 8 year old kid, but ended up wearing them because they fit me better. for a 38" waist 2X is recommended but get an XL) But if you are very experienced and dont mind being sucked in than go 3 sizes down. The best ! She can go 3-4 hours in a master class and they are not tight. Perfect shoe!
