I was looking for a comfortable sandle that wasnt a flip flop type of sandle. Just like with Ugg products you need to wear them to mold to your feet due to all that warm fur on the inside. Possibly detrimental for those who use this headset in areas that are very dusty, but I honestly dont see that happening. I found the only hole and dumped bike and all. Very happy so far. But this design works well because there is space for my bust. The first pair was sized XL mens, it lasted about 6 years. i even tried getting one size bigger - and its still bad. I prefer the tighter base and clear highs and high-mids. Mounting the rack to the rails does take patience.
