Have had a few questions on these... The XT was the plug Tecnica prior to the Diablo Race's introduction last year. These are two year old model boots, but have never been skied or used at all. I purchased them last spring as a spare pair, but have no use for them now that Jeff has moved me to a different boot. I won't be selling the ones that I had fit to me!
The XTs have a wonderful progressive flex, are great for skiing all over the mountain, have a lot of lateral power, and are low volume and fit close to the foot and leg. Definitely worth a consideration.
