Dated seller observations, not live quotes. Prices can change; tax and delivery are extra. Match the exact package shown below.

Choose the shell around your foot, then tune the flex

Start with an in-person shell fit in thin ski socks. Mondo length is only one measurement: heel pocket, instep, forefoot, ankle, cuff shape and range of motion all affect the result. Last widths are reference measurements that change with shell size, and flex labels are useful only as rough comparisons within a brand. Heat molding and footbeds can refine a suitable shell but cannot rescue the wrong size or volume. Before skiing, have a qualified shop confirm that the boot's GripWalk sole works with your binding and perform the required binding release check. We have not skied, pressure-mapped or durability-tested these boots.

ATOMIC

Hawx Prime 110 S BOA

Medium-volume feet and a balanced 110 flex

Research pick
ATOMIC Hawx Prime 110 S BOAPhoto: Atomic
Cost to compareCheck current price

Check Amazon for the current price of the Hawx Prime 110 S BOA men's alpine ski boots; exact ASIN B0F9LT3FBZ. Select the professionally fitted size; not Prime 100/120/130 or Magna/Ultra..

Atomic positions the Prime as its medium-volume Hawx shape. This 110-flex version combines a 100 mm reference last with a BOA lower closure, heat-moldable Mimic Gold liner and Memory Fit shell work, making it the broad all-mountain starting point in this shortlist.

  • 100 mm reference last; medium-volume fit
  • 110 flex; 1,962 g per boot at MP 26/26.5
  • BOA H+i1, Mimic Gold liner and GripWalk sole
The tradeoff

A 100 mm last is a reference at one shell size, not a promise of fit. The 110 flex may be too demanding or too soft depending on the skier, and BOA adjustment cannot correct the wrong shell length or volume. Have the supplied GripWalk sole checked with your binding.

SALOMON

S/Pro Supra S BOA 100

Medium-volume feet and a more forgiving flex

Research pick
SALOMON S/Pro Supra S BOA 100Photo: Salomon
Cost to compareCheck current price

Check Amazon for the current price of the 2026 Salomon S/Pro Supra BOA 100 GW men's alpine ski boots; exact ASIN B0GL93G48S. Select the professionally fitted size; not the older 110 listing..

Check Amazon price ↗Affiliate link · We may earn a commission.

Salomon lists a 100 mm inclusive last and medium stiffness for this 100-flex boot. Its lower BOA closure works with the ExoWrap shell and heat-moldable S/Pro CF liner, so it is the lower-flex medium-volume comparison beside the stiffer Atomic and K2 options.

  • 100 mm inclusive last; medium width
  • 100 flex; 4 lb 1 oz per boot
  • BOA closure, Custom Shell HD and GripWalk sole
The tradeoff

Flex numbers are not standardized across brands, and easier flex does not establish better comfort. The current exact model is article L45420800; retailer listings for older S/Pro Supra BOA versions can look similar. A fitter still needs to assess length, instep, heel and cuff shape.

K2

Recon 110 BOA

Medium-volume feet with a lighter-feeling shell

Research pick

Check Amazon for the current price of the K2 Recon 110 BOA men's alpine ski boots, selected 28.5 listing; exact ASIN B0FB941LH1. Choose the professionally fitted size..

Check Amazon price ↗Affiliate link · We may earn a commission.

The Recon uses K2's 100 mm medium-volume fit with a 110 flex, BOA lower closure and a fully heat-moldable shell and cuff. The LuxFit Pro liner and lighter construction make it a useful alternative for a medium-volume skier who wants response without moving to a 120 or 130 flex on paper.

  • 100 mm medium-volume last
  • 110 flex; sizes 24.5–30.5
  • BOA closure, LuxFit Pro liner and GripWalk sole
The tradeoff

The Amazon link is an exact Recon 110 BOA listing with a selected 28.5 size; choose your fitted size instead. Lower weight does not establish warmth, comfort or durability, and the liner and shell should be molded only by someone who knows the process.

K2

BFC 100 BOA

Higher-volume feet and easier entry

Research pick

Check Amazon for the current price of the K2 BFC 100 BOA men's alpine ski boots, Black/Blue selected 29.5 listing; exact ASIN B0D7VXKF7Y. Choose the professionally fitted size..

Check Amazon price ↗Affiliate link · We may earn a commission.

BFC is K2's high-volume alpine line. This 100-flex version combines a size-dependent 100–103 mm last with a BOA lower closure, heat-moldable CushFit Plus liner and hands-free entry feature, so it is the widest and most access-focused choice here.

  • 100–103 mm high-volume last, depending on size
  • 100 flex; intermediate profile
  • BOA closure, heat-moldable shell and GripWalk sole
The tradeoff

High volume is not a shortcut for buying too large. The exact Amazon listing has a selected 29.5 size, and another size must be chosen after fitting. K2 instructs buyers to have a qualified retailer check boot, sole and binding compatibility before skiing.

Hawx Ultra 110 S BOA

Research pick

Atomic's Ultra shape is the narrow counterpoint to the Prime and BFC. The 98 mm reference last, 110 flex, BOA lower closure and Mimic Gold liner make it the shortlist candidate for a skier whose foot and lower leg truly match a lower-volume shell.

  • 98 mm reference last; low-volume fit
  • 110 flex; 1,909 g per boot at MP 26/26.5
  • BOA H+i1, Memory Fit and GripWalk sole
The tradeoff

Do not choose a narrow boot from the width number alone. Instep height, heel shape, calf geometry and shell length can rule it out. The Amazon link opens a selected 27/27.5 listing; use the size established during an in-person fit.
