als, i never have a poblem with shin splints in my scarpas, or any other footwear and i have a moulded insole with a heel lift attached.

like reiver, i get "splints" in the outside of my calf only when skiing due to my leg being permanently kept in one position by the ski boot.

the ONLY time i start to get splints is when i walk too fast or too longer stride (never when out for a day though because i never do either of those).

i come down on the side of technique. for walking just try walking slower/shorter strides and see if it happens again. once you get a comfortable, relaxing stride going you'll find that you can go faster anyway.

PA, maybe try free heel gear if this is a problem that's lowering your enjoyment as you can move your legs around a lot more.  It's more difficult, of course, but not so difficult as to necessarily be problematical, and it opens up the telemark avenue for extra style points.  Note that you don't have to tele on tele gear, alpine turns work too so you can wedge, stem and parallel using the techniques you're used to.  You'd need new boots and bindings too, but you can use alpine skis with no particular problems.

what are shin splints?

a

Shin splints are micro-fractures in your tibia, that casue a symptom of pain in your shins every time your leg impacts the ground.  Not much fun...
