I'm on my feet for 12+ hour shifts, these socks significantly reduce the pain in my legs and feet after long shifts compared with normal sport socks. I've got great shoes, but these socks really make a difference. I'm impressed. You don't even realise your legs get sore until you try this type of sock and compare how you are at the end of the day. Haven't worn them in the Aussie Summer yet, but they've been excellent under scrubs over Autumn/Winter here.
