I've tried many different brands and feel like they've all been a waste of money except for these.  Unfortunately 2/3 pairs have disappeared in the laundry but that's a whole other can of worms.  I don't have unusual feet (size 7 1/2 - size 8 depending on the shoe), have a normal arch, regular width, and every now and then will let my toe nails grow a little.  I have not had any problems with these socks at all.  No holes, no slippage, and moveable/adjustable to hide under different shoes.  They stay put and have been wearing mine for over a year now.  I'm actually about to order a new set set to replace my missing ones.  I'm seriously just waiting for black, brown, or gray to come out... as long as these are made, I will continue wearing them.  I'm a very happy customer and big fan of these socks.  Wish I could feel the same about my washing machine...
