K2 Spyne 110 -how big would you go for shell sizing with intuition type liner?

post #1 of 9
Thread Starter 

Hi, looking at k2 spyne 110 as it has intuition type liner and it follows the side profile of my feet reasonably well, but for the 26.5 (306BSL) my toes are crowded and big toe would need a substantial punch whereas the 27.5 (316BSL) gives toes lots of room as I am just brushing the end of the liner in neutral position. I'm typically in a shell with 311ish BSL as 306ish tends to be too problematic. The 27.5 uncooked is what I would call comfy, and am wondering if it is indeed possible to have a comfy high performance boot with toe space using the intuition style liner. With a reg liner I would want a denser/snugger fit out of the box all the way around, though reg liners typically only last me part of a season of skiing. I have no idea what to expect from the intuition type liner after is cooked, and if it snugged up a bit and ended up feeling denser I would consider it. Needs to stand up as well I ski 50-65 days a year and do not want a mush liner in the spring.

 

Like the idea of giving intuition type liner a try and of having toe space with the 27.5 due to ingrown toe nails and tendency to have numbness/cold/frozen toes. Coming of a pair of Tecnica Demon w.  soft foam custom injected liners and tongues which I find cold and whose neoprene toe boxes didn't really give enough to keep my toes happy.

 

So any thoughts on how big I can go for shell sizing with this K2 as I intend to go back and do a closer inspection of the shell fits.

 

Thanks

what is the shell fit like on either one?

 

odds are you will need the smaller size.   intuitions dont take up any more or less space then any other liner

Hi. The 26.5 is about 9-10mm, the 27.5 about 19-20mm. Lateral width in both shells is good. With a thicker footbed in the 27.5 it is a reasonable volume giving good contact from metatarsal heads back, over the instep and up the front of the leg shaft, but toes feel like they are unrestricted which is a nice but weird feeling (with a thin footbed it has too much volume over the forefoot). The liner is not what you would call dense or stiff though, so it is  a bit hard to judge what it would be like after being skied for a significant amount of time. 26.5 has tight toe box and toes are slightly curled w boot fully flexed, so would need whole toe box enlarged by comparison, which is a familiar feeling (unfortunately). Ankle bone would probably end up needing punch or grinding near rivet due to low density of liner.

 

I tend to go into long 26.5's (310ish BSL) and have the toe boxes bumped in width and length where needed, but the liner's neoprene toe box never wants to stretch as big as the punch so the toes are still squished together, so curled red and purple toes are the norm. This long shell (27.5) with thick footbed fits better in volume than most (almost all) 26.5,s which is what I am finding really weird as it goes against the norm. The extra space is really appealing with ingrown toe nails, and with a few of my toes wanting go white and waxy even above freezing -I even use heaters for spring skiing.  

 

Will be checking out Tecnica Mach 1's as well (hopefully).

 

Thanks

dont worry too much about the BSL,  you should focus on the inside measurements (like the shell fit)

 

I would vote for the 26 shell with a 10mm shell fit for you.   and get a toe punch if needed

For BSL I find Tecnica tends to be the oddity as they usually have some models that BSL's are 5mm off from the norm, and that translates to a long inner shell size when comparing equal mondopoint sizing. I hope to check out the Mach 1 as it fits long for its mondopoint size.

 

For the 26.5 K2 my gut tells me you are right, I would never expect such a good fit in a big boot though, and it is tempting as it would be so freaking comfortable when doing course official duties.

 

Thanks

if you are in alberta, I'm in banff, and Soul has a bunch of technica AND the spine.

Update -got Tecnica Mach 1's. Will add comment later when I have time.

Expanded purchase update. Comparing the Tecnica Mach 1 to the K2 spyne, the Mach I has a longer shell fit for equal mondopoint size -about 4-5mm I'd say, so its like getting a true half size more than typical shells. The medial side of the Spyne followed my duckish foot profile slightly better and I really liked how it hugged my profile, but I'm still quite close in the Mach 1. In general width Mach is slightly wider, though ankle/rivit pockets are better profiled to fit ankle bones (spyne had sharper edge on ankle/rivet pocket that would have needed punch or grinding for me when liner packed).

 

Height in Mach 1 is greater, so am using supplied boot board shim plus additional layer. Will play with this, and is nice that the shim is screwed to boot board as shim will stay fixed in place and additional shimming can be put underneath so it too will be fixed in place. Heel does not quite feel fully back on long foot yet, so  boot may or may not need toe punch for first toe length and 5th width, which for me is unusual as I always need punch for first and 5th on long foot -so toe box definitely has more space than typical and is starting to narrow later giving more space for my 5th toe. Heel pocket seems reasonably deep in shell, so hopefully as it packs in I will get more heel lock as well.

 

Instep has more height allowing me to really crank down on the top 2 buckles to help hold leg shaft tight near ankle without collapsing the lower shell on top of my arch. Even then I am actually tightening the 2 forefoot buckles with pressure which for me is abnormal, so my boots may not leak for a change.

 

Coming from soft foam injected custom liners, the EVA foam feels soft, though I think Tecnica may be firmer than the K2 intuition liner.  Think this is more of a comfort fit than what I would like for skiing and not as precise as what I am used to, but will tweak the volume and wait and see how it breaks in and how they grow on me. Will probably add custom injected liner and tongue to get proper precise fit, and this shell will be a good starting point for this. The boots are on the soft side and that is probably partially attributable to the softer liner, so custom liner will stiffen it as well.

 

Wish the liner had heel strap to make it easier to pump the liner, and on a boot of this nature I would expect it.

 

Cheers
