The Tecnica Mach BOA MV — the women's 105 — swaps the two lower buckles of a conventional boot for a BOA dial and a steel lace, cinching the lower shell with an even wrap across the instep that you can micro-adjust both ways on the fly, gloves on. Two aluminum buckles handle the cuff. This is a women's-built boot, not a shrunk unisex one: a shaped women's cuff with a reinforced back spine, a Mechanic Cuff Adapt mechanism that tunes calf volume — not forward lean, which is fixed at 12.0 degrees — a heat-moldable C.A.S. PU shell, and a warm Celliant liner.
At flex 105, the Mach BOA sits at the top of Tecnica's women's MV BOA shell — an advanced and ambitious-intermediate boot, not a soft one. Reviews of the same-name boot describe a smooth, even flex that stays supportive rather than harsh, with strong edge grip and lateral stability leaning into a turn. Read the on-snow notes as platform inference: we did not find an independent test of the 26/27 build, so the feel carries over from the 25/26 same-name boot on the same last, BOA lower and women's cuff.
This boot is a fixed-cuff alpine tool for the frontside and mixed all-mountain resort snow. Its GripWalk soles help you walk the lot and the lift line; there is no walk mode and no tech inserts, so it is not a touring boot.
The one call to get right: the BOA lower shell fits roomy. Testers call the lower massive, an MV-HV hybrid, noticeably more spacious than the buckled Mach1 MV, while the women's cuff runs tighter. That pairing flatters a wide forefoot set on a slim lower leg and is wrong for a narrow foot, which will swim in the lower even cinched down. Route this boot by fit shape first, not by the 100 mm number.
So the Mach BOA routes by foot. A narrow or precision-first foot belongs in a buckled Mach1 MV 105 W — same last and flex, four buckles, a tighter lower. A genuinely wide foot or high instep goes to a Mach BOA HV 105 W, built on a higher-volume last. Want a dial on the cuff too, not just the lower? The Salomon S/Pro Supra Dual BOA 105 W runs BOA top and bottom. Need to tune your stance? The Atomic Hawx Prime 105 S BOA W adjusts forward lean and flex, where this boot's lean is fixed.
PTO carries the Mach BOA from 22.5 to 27.5 in half sizes, and it sells for $799.99. Tecnica does not publish the reference size behind either the 100 mm last or the 1690 g (per boot) weight, so read both as a class rather than a promise. The C.A.S. shell punches and the liner bakes, so plan on a shop bootfitting to finish the fit before your first day out.
Strengths
- +BOA dial wraps the instep evenly, glove-adjustable on the fly
- +Women's cuff with back spine and Cuff Adapt calf tuning
- +C.A.S. shell heat-molds and punches; liner molds to shape
- +Warm Celliant liner; smooth, supportive 105 flex
Best For
Advanced and ambitious-intermediate women with a medium-volume foot — especially a broad forefoot above a slim lower leg — who want an even BOA wrap on the lower shell, a warm women's-specific fit, and who treat a shop bootfitting as part of the buy.
Limitations
- −BOA lower runs roomy; wrong for a narrow foot
- −Fixed 12.0° forward lean; cuff is buckled, not BOA
- −No independent 26/27 on-snow test; feel inferred from platform
- −Tecnica does not publish the weight's reference size
Not For
Narrow or low-volume feet — the roomy BOA lower lets them swim, so they belong in the buckled Mach1 MV 105 W or a narrower last. Genuinely wide feet or high insteps go to the Mach BOA HV 105 W. Not for skiers who want a stiffer race flex or a softer beginner flex, who prefer traditional four-buckle lockdown, who want BOA on the cuff too (Salomon S/Pro Supra Dual BOA 105 W), or who need adjustable forward lean (Atomic Hawx Prime 105 S BOA W). And not for touring, or for anyone dropping these into bindings without a certified technician confirming the GripWalk sole match first.
Common Questions
- How does the BOA lower work, and how many buckles does it have?
- A BOA dial and steel lace close the lower shell in place of the bottom two buckles — push to engage, turn to tighten or loosen, pull up to release, gloves on. Two aluminum buckles close the cuff. So it is a BOA lower shell plus two cuff buckles, not a three- or four-buckle boot. One thing to know: the BOA lower fits roomy, more spacious than the buckled Mach1 MV.
- Who is the 105 flex for?
- Advanced and ambitious-intermediate women who actively drive the boot. 105 is the top of the women's Mach BOA MV shell — supportive and smooth rather than harsh, but not a soft beginner flex and not a stiff race flex. A cautious intermediate should look at the softer Mach BOA 95 W; there is no stiffer option in this women's BOA line.
- How is it different from the Mach BOA 95 W and the buckled Mach1 MV 105 W?
- The Mach BOA 95 W is the same platform with a softer, more forgiving flex. The buckled Mach1 MV 105 W is the same 100 mm last and 105 flex but uses four buckles and a tighter lower shell instead of the roomy BOA lower — that is the boot for a narrow or precision-first foot who wants a locked-down lower.
- What bindings work with the GripWalk sole?
- The GripWalk (ISO 23223) sole pairs with a GripWalk-compatible or MNC/Multi-Norm binding that accepts GripWalk soles. A conventional alpine ISO 5355 binding without GripWalk certification will not accept it, and there are no tech inserts for pin/touring bindings. Have a certified technician confirm the sole-and-binding match and set your release before skiing.
- The last is 100 mm — what foot shape does the BOA version suit?
- 100 mm is a medium-volume class, but the BOA lower shell fits roomier than the number suggests — testers call it an MV-HV hybrid — while the women's cuff runs tighter. That combination suits a broad forefoot carried above a slim lower leg. A narrow foot will float in the lower; a genuinely wide or high-instep foot wants the Mach BOA HV 105 W. Final fit is decided by a shell fitting, not the number.
