I'm on my last pair of old style Smartwool Adrenaline Mini-Crews I purchased a couple years ago. I was going to purchase another 8 pairs but noticed they now have a new style called PhD's. Anyone prefer the PhD over the Adrenaline? Where might the best place online to purchase a large quantity of sock's be?
(I dealy love my wool Injinji's but the color's stink. I'd prefer to purchase 8 pairs of the wool mini's but they only make them in black or green, no grey. Blah!)
