very happy with purchase. When they arrived, I just loosened the straps by one notch and shuffled myself all over the place, even the Atlanta Zoo, which is lovely, but ridiculous with the hills. Otherwise, I wore them to a wedding and survived a few hours of standing and a couple more of dancing without any pain or discomfort! Next I put my axle bar into the T bar, It went in nice and snug. So take a look at the replacement model: Sennheiser PX 100-II On Ear Miniheadphone (Black) by Sennheiser . I use round weight plates and can only get two dumbbells on each side, I guess if you use hexagonal weights you would get four on each side. Da ich aber keinen besonders dicken Fuß habe ist dies kein Problem für mich. LOVE LOVE that Amazon has free shipping and free returns. Quality on this wasn?t great. Simple mente fantastic
