I never had sore calf muscles with my old Lange heated tch something or
others but then again that was before I bought new shaped skis and started a
regular exercise routine and started skiing with more skill .

When you were a less acomplished skier youe technique wasn't polished and
you were probably using more muscle that finesse so your legs should have
hurt more. You also didn't have shaped skis so you had to work harder to
turn your skis. Then you wrote that you started a an exercise program and
now your calves hurt. And that with your old boots you had now claf strain.

Without a doubt I can tell you that your claves hurting are your boots. You
have too much forward lean built into the boot. When you're on the flats or
waiting on a lift line you can't get out of the crouched position and relax
you legs. I had the same problem with a pair of Tecnica RX Ultrafits. I
sold those boots and bought a boot that had less forward lean. Now I have no
more calf burn. My wife changed boots and her new boots have more lean and
she complains of calf burn too. You have two choices. Build up your calf
muscles or buy new bots. Salamon may make a boot that has less forward
lean. I also notice that if the boot has a ski/walf function that the boot
ususally has less lean.

Good luck!!
