With the volcano in Iceland nixing my plans to climb in
Chamonix earlier this spring I had some time and money on my hands and no place I really wanted to go. That is a dangerous combination!
Daniel
Harro's email last month and pictures of the work done on his
Spantiks got me thinking.
The
Baruntse gives my foot a great fit and offers a full length, rigid, nylon
midsole so it front points very well. I like the support, lacing and cuff better for my foot than the
Spantik. The over all warmth of both boots I suspect is very comparable with similar upper design and materials.


The obvious advantages of the
Spantik is it has a foam
midsole for extra warmth on top of a carbon fiber
midsole used to cut weight and add rigidity. The other thing
Sportiva used in the
Spantik design is a very thin
Vibram sole to also lower the weight.
After seeing what cobbler Dave Page of Seattle did to Daniel's
Spantiks by adding a Nepal
midsole and big block
Vibram sole it got me thinking. Wrong direction for Daniel's
Spantik imo by adding the weight of a Nepal sole/mid sole and duplicating the Baruntse combination, but how about going the other way and dropping a few ounces?

I took my
Baruntses down to Dave Page's one afternoon and described what I wanted. Dave pulled out a couple of different
Vibram sole options. I had brought along a accurate electronic scale to see if the weights "added up". And sure enough, it looked like a resole with the "proper" La
Sportiva Vibram would drop 4oz per boot and add more insulation under foot while doing it. ( I didn't think the added insulation was needed but..if it goes with a weight drop why not?)
I ended up with a
Baruntse that weights in at 2# 15.5oz compared to the factory
Spantik at 3#.05oz. A total of 1.5 oz difference.
Spantik has a 26mm mid sole at the ball of the foot and my
lwt Baruntse has a 25mm
midsole thickness in the same place.
Original La
Sportiva factory, size 45, weights:
Spantik 3# .o5oz
Baruntse 3# 2.50oz
semi custom boot weights:
Spantik with a
Baruntse liner 2# 13.5oz
Baruntse w/inner and
lwt sole 2# 15.5oz
I ended up dropping only 3oz per boot but I did gain some sole insulation as well. The new lug pattern has a sold toe areas and will be better for pure rock climbing. Certainly more cushion in the boot now, both in the sole sole and heel. Down side? The
Vibram soles are thinner so they won't last as long on hard surfaces. Same durability issue on a
Spantik as well. But the
Baruntse has more surface area being used on the newer sole.

I like climbing technical ground in the
Baruntse better than in the
Spantik so it is a win/win for me. And even with the resole I am still almost $200 under the
Spantik retail. Would I do it again? Cost was $78.00 for the resole. No real reason to do it other than curiosity on my part to see what kind of weight loss I would come up with. But if I wanted to take the
Baruntse on a cold, technical Denali route, I would do it again in a heart beat. No question it is less weight and a warmer boot now. Warm enough to leave the over boots at home above 17K.....may be :)
This is an modification that would cost La
Sportiva nothing in production and it would offer us one more option for dbl boots.
