On the plastic Tecnica measuring device I was 28. I wear an 11 1/2 to 12 street shoe, never a 10 1/2 or 11, as the mondo to US size chart would suggest. Does this mean I should be looking at 27 size boots? 27 shell fit gives me about half a centimeter behind heel. Boots feel real short with liner. A little more info: I'm 6', 200lbs, advanced to expert, aggressive skier, with thin lower leg. Boot I'm looking at is the Mach 1. Have had 2 different pairs of Tecnica's for last 15 years (10 yrs on current Diablo's which are 28.5. Have loved them, but do feel I always feel I want to crank buckles really tight.
Thanks for your time.
