ski boot blister question

One thing I wonder about -- given the location of the blisters -- is whether some adjustment in your gait might help -- How much lifting the ski off the snow on each stride vs sliding the the ski forward ?   Lifting the ski seems like it would contribute to movement / friction within the boot in that location.

Back in the day when I was stronger and faster (12-16 mi tours) I would just let them heels blister, bleed and finally callous up. At the end of the season say like August that callous would just fall off. Today I'm a big fan of previously mentioned Leukotape.

One tip with Leukotape (which you'd figure out soon enough on your own) - it does not stretch. At all. So you if you put it on skin which is stretched in normal foot movement, you want to position the foot to stretch the skin while applying it. Otherwise you will find out just how well the tape can immobilize a body part!

I got a wicked blister from touring with my instep buckle undone. It caused my heel to lift which allowed my inner heel to rub up and down against the liner which caused the worst blister I've ever had in my entire life.

I had to wear crocs for a month the spot was so bad. Ever since then I make sure my instep buckles are nice and snug so it restricts the heel movement.

Lot's of good experience here.  I'm pretty good about keeping my skis on the surface when possible, and just sliding, unless it's steep.  I do tour with my buckles undone, though, so maybe that is the culprit.  I'm definitely going to pick up some leukotape.  At least this looks to be a good, long touring season to try out some adjustments!

Good to know.   Which Scarpas?   I have a pair of Scarpa Rush

I only unbuckle the top buckle for touring and leave the instep and ankle buckles fastened (I've removed the "power strap" completely)
