I have worn Thorlos for over 10 years. They are quite expensive, so I don't have many available to me for running or working out. I am a heavy guy - 235 lbs, 5' 8" - and suffer from overpronation and flat feet. Wearing Thorlos, therefore, is a therapeutic "treat" for my feet. I've owned several varieties of Thorlos. I decided to try this Experia CoolMax sock and see if it retained the cushioning advantages of the more widely-available Thorlo socks in a thinner overall package. Unfortunately, it doesn't quite achieve the level of cushioning I was hoping for. The cushioning is adequate, however, but it's not nearly as "plush" as their other non-CoolMax products. I will say that the CoolMax technology works in terms of lessening the heat and eventual sweat around my feet. If you require a thinner sock with acceptable cushioning and excellent cooling properties, this is the sock for you. If you need more cushioning, stick with the running or walking socks from Thorlo.
