Find your starting size, understand boot fit, and choose with confidence. This guide covers alpine ski boots for adults and juniors. Always check the individual product’s fit volume, flex and sole standard before ordering.
You’ll need paper, a pencil, a ruler and a hard, level floor.
Also measure the widest part of your forefoot. Length helps identify size; width and foot shape help identify the right boot.
Ski boots use Mondopoint, usually shown in centimetres. A foot measuring 26.5 cm corresponds to a Mondo reference of 26.5. This is a starting point for fitting, rather than a guarantee that every boot in that size will fit.
Measure your feet instead of relying on your everyday shoe size. US, UK and European conversions vary between manufacturers.

| 18.0 | 180 | 18.0 |
| 19.0 | 190 | 19.0 |

Between sizes? Ask for fit advice before rounding up. Many boots share a shell across two neighbouring sizes, such as 26/26.5. Shell groupings and liner or size-adjuster arrangements depend on the model. Not every listed size is available in every boot.
Last width describes the boot’s forefoot width at a specified reference size. Compare the manufacturer’s stated size as well as the number. Instep height, heel shape and calf fit matter too. Adding length to solve a width problem can leave the heel loose.
Try boots indoors with one pair of thin ski socks. Fasten the buckles or BOA system with moderate tension, then flex forward several times.
Liners settle with use, but don’t assume a painful fit will resolve itself. A boot fitter can assess the shell and advise on suitable adjustments.
A lower flex number generally means a softer boot; a higher number generally means a stiffer boot. The right choice depends on your ability, weight, strength, ankle mobility and skiing style. Flex numbers are not standardized across brands, so use them as a comparison point rather than a universal scale.
Read the boot’s sole standard and your binding’s compatibility information before pairing them. Alpine, GripWalk and touring soles are not automatically interchangeable. Have your setup checked and adjusted by a qualified ski technician.
Measure children’s feet again before each season. Choose a junior model with suitable flex and confirm that its sole standard is accepted by the binding. Ask for fitting advice about growth allowance rather than buying substantially oversized boots.
Contact The Drop with your foot measurements, usual boot size, skiing experience and the models you’re considering. Measurements help narrow the options; trying boots with a qualified boot fitter is the best way to confirm the fit.

The AR ONE 110 is the smooth-flexing, do-it-all boot. Top shelf features like the Team Liner, Team Elastic Cam 50mm Power Strap and the Kush Damping Bootboard give the AR ONE 110 a plush, supportive feel and customized fit that’s a favorite of our freestyle athletes. It’s the perfect blend of comfort and control to take the sting out of heavy landings and high speed chatter.
