Stay warmer and go further.
Short tours are great, but the longer missions are the ones that stick with you. Sometimes it's because they're the most fun, but other times it's because you're suffering though frozen toes for days at a time, which is memorable for all the wrong reasons. Dynafit's Winter Guide GTX Ski Boot will let you enjoy long tours and cold days in comfort, though, with a Dynafit Custom Ready liner that's outfitted with a Gore-Tex Duratherm L membrane to keep your toes warm and dry when you're spending hours digging pits, sleeping at 13,000 feet, or heading out for a day of making pow turns at -15F.
There's more to the Winter Guide than a warm and dry liner, though. Like any Dynafit, it can climb like a goat, with an Ultra Lock System 2.0 ski/hike mode that toggles between a locked and open cuff with the flick of a single switch. When it's open, you have 60-degrees of super-smooth cuff rotation for easy skinning and bootpacking, and when it's closed the Driving Spoiler 2.0 provides bomber skiing performance. The spoiler also has an insert that lets you choose between two forward lean settings, and the cuff cinches down via Dynafit's Ultra Lock power strap, which can be loosened up with a quick pull for faster transitions. The Winter Guide also features the Buckle Cable Retention System, which folds the buckles flat against the shell when they're open to prevent snags, and Dynafit's Quick Step-In tech inserts to make stepping into tech bindings a breeze, even in deeper snow.

- Q & A
- Familiarity: I've used it several times
Been on 8-10 tours with these bad boys. Some long days on a recent hut trip, and they are incredibly comfortable. I have worn them 12-14 hours at a time no worries. Super quick transitions with the quickdraw power strap. Downhill performance isn't as good as some, but there is enough stiffness for performance. Uphill performance is awesome - The lace system for the liner keeps you tight even if you want to loosen the middle buckle for comfort.
Only thing I was really worried about was sweating and the goretex liner sealing in any moisture - No problems thus far.
What is the last for this boot ,or the mm in the toe box and volume rating. Size 29.5
The Winter Guide GTX Boots have a 103 mm last and a thermo-moldable liner for a more customized fit. Feel free to contact me directly with any more questions about these or other ski boots.
