I have thick, coarse hair. The sizing for these was very confusing for me I actually thought I was buying a uk size 10 and ended up with I think is a size 7 or 8 just gave them to someone they fitted but very very comfy. Side and back sleeping were pain free for first time in years. Super cute, fits as expected. Their overall look is classic, these look like old school leather shoes, the sintetic padding is hidden, the little hook and strap are nice touches, overall gorgeous. Will they last as long as real Birks? Possibly not as long, but for the price, they are absolutely worth it. I mean, theyre cute, their packaging was A+ and they dont look that bad on the black razer Kraken. Audio: The stereo surround sound is good, and I can clearly hear the player crawling. The straps are soft and do not cut into your foot. Each hole in the frame/rack assembly takes one bolt, 2 washers, and one locking nut.
