I use these ratchet straps on my ladder racks on a very frequent basis. #MakeInIndia Im hoping that by washing them they fluff back up a little, but I will see soon. They?d make a good water shoe too as they wash easy. its that type of feel. I have heard this type of hiss in other products in the $250 to $500 range but at over $1k and the fact bose does not have this problem in any of their other products is quite baffling. They are very comfortable, the battery life is pretty good, over 6 hours the first couple times I?ve used them. It is very comfortable to wear, even with glasses. The bottle was leaking and appeared to already be used when I got it. So, like most Birkenstocks they do fit a little big, but other than that, they are very nice quality shoes, I like this sandals because they are totally different from your regular Birks, you can wear them all day (and night) without any problems.
