Ski bindings, ranked on the two numbers that decide whether one fits you

The DIN range, and why the number is not the point

Every alpine binding publishes a range - 3 to 11, 4 to 13, 6 to 16. The number people fixate on is the top of that range, and the number that actually matters is the bottom.

Your release value is calculated from your height, weight, boot sole length, age and skier type, using a procedure published in an international standard. The DIN chart page walks through the five inputs. For a large share of recreational skiers that calculation lands somewhere between 4 and 8. A binding that starts at 6 cannot be set to 5, and no amount of wanting it to will change that.

The sole standard, which is where buying separately goes wrong

Ski boots come with soles built to published norms, and bindings do not accept all of them. The short version: ISO 5355 is the traditional flat alpine sole, ISO 23223 is the GripWalk sole with the rockered rubber tread, and a touring sole under ISO 9523 is a third thing again. The sole standards page explains which marking means what, and it is the page to read before you buy a boot and a binding in separate transactions.

What matters here is how a maker tells you. Marker publishes a Boot Type field reading “Alpine, GripWalk”. Tyrolia goes further and publishes the standard numbers themselves. One of those is checkable against the stamp on your boot; the other asks you to trust a logo.

Brake width, the third number

The brake is the pair of sprung arms that drop and stop a released ski sliding off down the hill. It is sized in millimeters and it has to clear the waist of the ski it is mounted on - too narrow and it will not go on, too wide and the arms drag in a hard turn.

Nobody on this page publishes a rule for how much wider than the waist to go. We looked, on all three maker sites, and found brake widths listed as options with no guidance attached. Your ski publishes a waist measurement; the shop mounting the binding will pick the brake from it, and that conversation is worth having before you order rather than after.

What this page ranks on

• 1. Published DIN range. It has to bracket your calculated value with room at both ends. This is the first filter and it eliminates more bindings than anything else.
• 2. Published sole compatibility. Which norms the binding accepts, stated in a way you can check against your boot.
• 3. Published brake widths. More options means it fits more skis.
• 4. Published weight. You lift it with every step of every traverse. Only one of these publishes a figure.
• 5. What the maker will not tell you. Warranty terms and certification references are absent across all three, which is worth saying out loud rather than quietly omitting.

The three, compared

That table has more blanks than a specification-led category ought to, and the pattern in them is the finding. Bindings are the one piece of ski equipment with a genuine safety function and a legally-set number on the side - and not one of these three names the standard it is certified to, or publishes a warranty term.

The picks

Marker Squire 11

The pick, on the range. Marker publishes 3.0 to 11.0 and - unusually - publishes the skier weight band that goes with it: 65 to 240 lb. Put those together and it is hard to construct a recreational skier this binding cannot be set for.

It also publishes the things the others do not. 820 g the pair. A 24 mm stand height, which is how far your boot sits above the ski and therefore how much leverage you have over an edge. A Boot Type field reading Alpine, GripWalk, so both common sole standards work. And three brake widths - 90, 100 and 110 mm - which covers a carving ski through to a mid-fat all-mountain ski.

Honest cons. Marker names no certification standard on the page - it publishes the DIN range but no ISO reference behind it - and publishes no warranty term. Its own page contradicts itself slightly, listing three brake widths in the size selector and a single 90 in the Brake Width field. And like everything here, it is hardware: a shop mounts it and sets it.

Tyrolia Attack 14 GW

The one to buy when compatibility is the thing you are unsure about, because Tyrolia writes it in the language of the standards rather than in logos: compatible with adult Alpine boots (ISO 5355 Type A) and adult Walk boots (ISO 23223 Type A). That is a sentence you can hold against the stamp on your own boot sole and get a yes or a no.

It publishes the widest brake range on this page too - 85, 95, 110, 130 and 150 mm - which means it fits skis from a narrow carver to a genuinely fat powder ski, and the adjustable AFD underfoot is the part that physically moves to accommodate the two sole shapes.

Honest cons, and the first is serious. Tyrolia publishes no DIN range on this product page. On a page whose first criterion is whether the range brackets your release value, a binding that does not publish a range cannot be checked at all before you buy - you are relying on the shop to tell you afterwards. It also publishes no weight, no warranty and no certification, and it is priced in euros on Tyrolia’s own store, so there is no US figure to compute a cost per day from.

Marker Jester 16

Marked as the skip above, and the reason is one published number: the range starts at 6. Marker’s own size chart lists the Jester 16 at DIN 6.0 to 16.0 and puts the matching skier band at 130 lb and up.

That is not a binding that is merely more than you need. A release value is calculated, not chosen, and if yours comes out at 5 then this binding cannot legally be set for you - there is no setting there. Most women, lighter men and every child fall outside it.

It is on this page because it is genuinely right for the skier at the top of the chart, and because it is the binding people buy on the assumption that a bigger number is a better binding. Honest cons beyond the range: Marker publishes no standalone product page for this model that we could read, so its brake widths, weight and stand height are simply unavailable, and there is no published US price.

What you are actually buying, and what you are not

This is the part that separates bindings from every other product on this site. A binding arrives as hardware. It is not usable until a shop has drilled and mounted it to your ski, set the release value from your measurements, and run a release test on a calibrated machine.

So budget for that. A mount and set is a shop service with a real price, and it is not optional - an unmounted binding is a paperweight and a wrongly set one is worse than no binding at all. The bindings explainer covers what the shop is actually doing and why the release test is the step that matters.

One more reason a shop is in this transaction

If the plan is to put a new binding on an older ski, or to have an older binding checked rather than replaced, expect the shop to have opinions. Shop technicians work from a list of models they will mount and test, and they decline the ones that have aged out of it - a binding is a set of springs, springs fatigue, and a release value that was correct six seasons ago is a number nobody can vouch for now. The explainer covers why the release test is the only meaningful check, and why reading a setting off the side of a binding tells you what it was set to rather than what it does.

That is also the honest answer to the secondhand question. A used ski with bindings already on it is worth buying only if a shop will agree to test them, and that is a question to settle before money changes hands rather than after.

When you should not buy a binding at all

Most beginner and intermediate skis are sold as a system: the ski arrives with a binding already matched and mounted on a rail, needing only a shop to set and test it. If that is what you are buying, there is no binding decision to make and this page is not for you.

• Buying a complete setup as a beginner? Take the system ski. The beginner ski picks are all system skis, and the matching is done for you.
• Replacing a binding on a ski you already own? This page is for you - but check the ski has enough undrilled material left for a new mount pattern, which is a question for the shop and not for the internet.
• Bought skis flat, or secondhand without bindings? Also you. Match the brake to the ski waist and the DIN range to your calculated value, in that order.

The package-versus-separates comparison covers the money side of that decision properly.

Who should buy what

• Almost everyone replacing or adding a binding: the Marker Squire 11. A published 3 to 11 range covers the overwhelming majority of calculated release values, and it is the only one here with a published US price.
• Unusual ski waist, or an uncertain boot sole: the Tyrolia Attack 14 GW, for five brake widths and compatibility published by standard number - accepting that you cannot check its DIN range before buying.
• A shop has told you your release value is above 6: the Jester 16 becomes the right tool rather than the wrong one.
• Buying a first complete setup: none of these. Buy a system ski and let the maker do the matching.
