A burly tech boot to drive today's modern skis.

Dynafit built the Mercury TF Alpine Touring Boot to drive modern skis with power and precision. With tech fittings at the toe, this boot plays well with your Tech bindings and ascends with the sort of efficiency that may lead you to believe someone installed one of those magic carpets to the top of the peak. 

A touring boot is worthless without the capability to flex freely in walk mode and offer rigidity in ski mode, things which the Mercury does handily. The shell benefits from the rigidity and weight savings of fiberglass-reinforced TPU at the heel, and the flexibility of molded Pebax from the front of the cuff forward. For skiers looking to maximize both the up and the down, the Mercury comes standard with a removable downhill tongue that can be switched in and out easily, even on the skintrack. A quick flip of a lever frees the cuff to rotate up to 60 degrees (total range, front to back) to take the stress off your shins when you're striding along on a skin track, or so you can freely move to achieve the perfect footing on a knife ridge or tight boot pack. The One Vulcan liner boasts a roomy 102mm of width, it can be thermally molded to fit the exact contour of your foot.

Just like its big brother (the Vulcan TF), the Mercury TF is compatible with Tech bindings and all types of alpine touring bindings. A Dynafit Pro sole gives you traction when you're out of your skis, and Dynafit's engineers included a few extra-rigid lugs to prevent flex or movement at the toe or heel when the Mercury is engaged in a more traditional alpine touring binding.

Excellent Uphill & Downhill Performance

  • Familiarity: I've used it several times

I've been waiting to write a review until I did a full day+ tour with these. Ive now put several short tours and a 9 hour day in on these boots. I've upgraded the liner to intuition pro tongues, just my personal preference.

Performance: Not as light as tlt-6 but still great performance going up with better downhill. I'm a large skier (5'11" 205lbs) and these give me enough stiffness to enjoy the down. I've tried the TLT-6 and they were not enough for me.

Fit: A little wider than the tlt-6 but still a tight heel fit. These have the best ankle/heel hold of any boot I've skied recently. My only wish would be a slightly higher cuff height.

Durability: I've had to do some bootpacking in these, and while the vibram outsole is holding up great (even when I had to hike 1.5 mi in on dirt/rock), the toe lugs are giving me concern for how soft the plastic is. I've had to toe kick some steps in and the toe lugs have noticeable divots in them. My only concern right now for durability is damage to the toe lugs.

Brilliant cuff design

  • Familiarity: I've used it several times

I can't say enough cool things about this boot. Stiffer than pebax plastic... legit. Extra cuff rotation makes it more comfortable for hiking .... yes. Burly stiff on the descent.... true. Top buckle doubles as the ski/walk mode switch.... brilliant. Light weight and wider last than other Dynafit boot... check. Five stars!

Are these boots compatible with alpine bindings?
