Kayland Hyper Traction Mountaineering Boot - Men's - 2010 BCS

Very warm boot. Stiff sole like all the Kaylands, bit of a funky tongue system. Fit is exceptional though. This one you'll want to try on and look at, as the lacing is "different" than any other boot I have tried.

These boots were made for my feet - narrow with slightly wide toes and a medium high arch.
The construction feels solid while the boots are relatively light. The soles are 2x4 stiff but the slight built in rocker eases the strain of long walks. The ankle support is pretty solid as well.
They are warm, but not super warm. If I am idle, standing still, then somewhere around 25F degrees my toes get a little frosty, but I usually have cold toes.
If Scarpa and La Sportiva almost fit, try the Kaylands.
UPDATE:
The Glen ice climbing area is a short half-hour hike uphill from the parking area in the Lehigh Gorge State Park. With the laces undone above the ankles, these boots hiked (despite stiff soles) almost as well as a real pair of hikers. When I got my BD Sabretooth crampons on (which fit perfectly) the boots ultra stiff soles really started to shine. I had no problem kicking in points or standing on them afterwards. All day. The heavily padded tongue took most of the brunt. Fruit boots notwithstanding, I can not imagine a more precise feeling boot.

This is one really awesome boot! I bought Hypertraction with for the purpose of winter mountaineering & ice climbing. For these purposes correct fit is essential as cold feet is the result otherwise. I have a slightly wide foot and my left foot is slightly bigger than my right. When it comes to American shoes, the difference is not noticeable and no additional consideration is necessary. But when it comes to mountaineering boots many Italian welts do not accommodate my width without creating detrimental length. I tried on many boots to find the correct fit and found 2 that suited my purpose and comfortably accommodated my feet. The Kayland Hpertraction and the La Sportiva Nepal EVO GTX are both really excellent boots. Even within the same manufacturer, like La Sportiva or Kayland, some boots fit my feet and others do not. For instance I can wear the La Sportiva Nepal EVO GTX but the La Sportiva Trango S EVO GTX is too narrow. I can wear the Kayland Hpertraction but the Kayland M-11+ is too narrow.

The Hypertraction is pricy but Kayland has spared no expense when it comes to the material used. Dryver®, eVent®, Primaloft®, Schoeller®, Vibram®, this boot has all of the best materials. The water-tight RIRI Aquazip fastening and Velcro top side seal off the boot interior and make a more comfortable fit at the ankles than any boot I have worn. The E.C.T. Traction multi-layered composite insole makes a great crampon shelf for front pointing.

I have used the Kayland Hypertraction for 2 winters on Colorado 14er’s and ice climbing in Ouray and never had cold feet.

so i just got these and have been wearing them around the house so far. first impression is that they are light and stiff. i am a size 9 in shoes and a 9 1/2 in every boot. went with the 9 /12 in these and they fit really well. the heel is not as tight or secure as the nepal evo(same size) but the footbox feels just slightly more roomy. the gator zip extends all the way to the toe box area, and secures fairly well around the ankle. have tried them stock, and with green superfeet, with a combination of socks and liners, tried smartwool mountaineering socks with liner and they have a really nice fit, same with a liner and mid wieght socks. i do feel that since the lighter construction that the nepal evos will be sturdier but the kaylands have a much shorter break in time. all in all really impressed but for my foot shape of slightly narrow with a narrow heel mi will be going with the nepal evos. the "walkability" of these on flat ground is almost as good as the evos, so long approaches on trail will be of little discomfort and technical ability with these being so stiff will be great.

Tried almost every other mountaineering boot that exists and these finally solved heel blister problems. The ankle retention system works great. As for overall fit, they have a narrow heel and wide toe-box with a very natural rocker motion sole. I always have cold toes, but have never thought twice about my feet when wearing these. Very toasty, but also breathe well when it is warmer on the approach. No wet feet in wet snow either. These are much warmer than the M11s and seem to have more cushion. I usually wear a W's 10 and the M's 9.5 fit great.

I had to return these to BC and order them from another company because the ones I got were too small, and BC was out of stock then. I normally wear a 91/2 to 10 EE, and found the 10 in these to be very, very small. They didn't even fit my feet barefoot! I had to go up to an 11 1/2 to fit with a liner and winter sock!
But, other than that, they seem to be amazing boots. I haven't had a chance to climb in them yet, but got them for cold weather, high altitude climbs of the Pac NW volcanoes (Hood, Rainier, Adams, Baker, Shasta, ect..). I was fed up with uncomfortable plastic boots, or cold, tired feet in light weight "hybrid" bbots. These seem to bridge the gap between. The only thing that could be improved is to make the liner boot removable. Very good construction, very stiff sole.
