tecnica 70 -19.0/20.0 is same shell 249mm,tecnica 70- 21.0 259m both are junior din sole. 22.0 shell is first adult norm.
tecnica 90 2.5UK 260mm shell is adult norm
lange team comp 266mm sole is adult norm and virtually same interior shell length as tecnica 90. ( a corvette is a huge car but still only seats 2) tecnica has more interior room per given shell length than some other brands ( Lange / Rossi for example )
the biggest issue you will encounter is that the bindings that fit junior soles are not suitable for J5 and older competition and the junior boot norm soles are incompatable with adult norm junior bindings. i see this issue all the time with the better athletes, its not about DIN settings but how the binding hadles the energy level and the math says an 80lb J5 or J4 at race speeds puts more energy into the system than their 140lb mom and the tiny boot sole doesn't ehlp the leverage factor either!!
tecnica 70 is a great boot but make sure you can get a binding that is up to the task!
shell fit is everything! go to your local race expert!
