Remember the Costco Head brand socks they used to sell...these are the closest I have found BY FAR!  I work in the refinery business and spend 12 hours in steel toed work boots, these are a foot saver.  My old pairs from Costco were getting worn out, these are a perfect replacement.  The part of the sock on the foot from heel to toe is thick and cushioned, much thicker than any other "work sock" that other companies claim.

p.s. they actually do sell Head brand socks on Amazon, identical to the Costco brand, they are just in black or gray only...do a search :)
