They were incredibly comfortable right out of the box! My foot swims in them and can not tighten the strap😩 adidas performance ultra4d Can hold up to 9 pair of shoes that are a size 13 and could more of you were a smaller size. Small detail, but I appreciate the softer side of the velcro is one the side that may come in contact with the lenses if you decide to change or remove it while on the headset. adidas performance ultra4d They stay in the ears very well, much better than the tethered earbuds these replaced. adidas performance ultra4d I wish I had glued it on with some tacky stuff when I thought about it. Because I figured theyd break in and Id be able to wear them, I wore them 3 or 4 times before giving up — far too worn to return. Removed the bolts as per instruction only to find the supplied bolts are way too thin in diameter and will not fit. adidas performance ultra4d I cant recommend this knowing I had similar sandals and slippers that lasted years at similar price. The fit is pretty spot on.
