Winter Mountaineering Kit: How to Choose Crampons and an Ice Axe

A Scottish hillwalker's buying guide to crampons and ice axes — the B/C boot-and-crampon rating system that stops your crampons falling off, and how to size a walking axe by height.

Quick Summary

  • The one thing you must get right is boot-and-crampon compatibility — match the crampon's C-rating to your boot's B-rating, because a mismatched crampon can come off on the hill, and that is a safety issue, not a comfort one
  • B1 boot → C1 crampon, B2 → C2, B3 → C3 — you can run a more flexible crampon on a stiffer boot, but never a stiff crampon on a flexible boot
  • Size a walking axe by height — hold it by the head at your side and the spike should reach your ankle; most people land at 55–65cm and want a straight shaft, not a curved climbing tool
  • Buy steel, 12-point, and matched to your boots — that combination covers almost all Scottish winter hillwalking; spend the money you save on a winter skills course

Crampons and an ice axe are the two purchases that turn summer hillwalking kit into winter mountaineering kit, and they are the two people most often get wrong — not by overspending, but by buying a crampon that does not match their boots. This is the one area of outdoor gear where getting the spec wrong is a genuine safety problem: a crampon that is incompatible with your boot can lever off mid-step on hard snow, exactly when you are relying on it. So this guide leads with compatibility, then covers how to size an axe, and only then worries about brands.

If you want the skills to use this kit — self-arrest, crampon movement, whiteout navigation — that is a separate and more important read: winter hill walking skills for Scotland. Kit without skill is just expensive ballast.

Quick Answer: For Scottish winter hillwalking, buy a steel 12-point crampon matched to your boot's stiffness rating (B1 boot takes a C1 crampon, B2 takes C2, B3 takes C3 — a more flexible crampon on a stiffer boot is fine, the reverse is not) and a straight-shafted walking ice axe of 55–65cm, sized so the spike reaches your ankle when you hold the head at your side. Budget roughly £100–180 for the crampons and £60–130 for the axe. Get the boot-and-crampon match right before anything else — it is the spec that matters for safety.

Boots first: the B-rating

You cannot choose crampons until you know your boots, because the boot decides which crampons will safely stay on. Winter boots are graded by stiffness on a B0–B3 scale:

Boot ratingWhat it isCrampon it takes
B0Flexible three-season walking boots — bendy sole, fabric or thin leatherNone (flexible walking crampons/microspikes only)
B1Four-season boots — semi-stiff sole, warmer, thicker upperC1
B2Stiffer mountain boots — very stiff sole, glacier and alpine use, heel weltC2 (or C1)
B3Fully rigid technical boots — often plastic, toe and heel welts, ice-climbingC3 (or C2/C1)

For general Scottish hillwalking — winter Munros, ridges, non-technical routes — a B1 or B2 boot is the sweet spot. B1 is the minimum that will safely take a crampon; B2 adds rigidity, warmth and the option of a clip-heel C2 crampon, which most people find quicker and more secure to fit. B3 is climbing kit — rigid, cold-footed on long walk-ins, and more than a walker needs.

Then crampons: the C-rating and the golden rule

Crampons carry their own rating — C1 to C3 — that tells you which boots they safely fit:

  • C1 — flexible crampons with a strap or basket binding over the toe and a strap-and-clip or strap heel. They flex enough to sit safely on a B1 boot and will also go on stiffer boots. The standard general-hillwalking crampon.
  • C2 — semi-automatic crampons with a flexible toe strap but a heel clip (lever) that engages a welt on the back of a B2 boot. Quicker and more secure to fit than a full strap system, and the popular choice for winter Munro-baggers with B2 boots.
  • C3 — fully rigid step-in ("automatic") crampons needing welts at both toe and heel, for B3 technical boots and steep ice. Overkill and, on a walker's boots, incompatible.

The golden rule of compatibility, stated plainly: you can put a more flexible crampon on a stiffer boot, but never a stiffer crampon on a more flexible boot. A C1 crampon on a B2 or even B3 boot works fine — you lose nothing on hillwalking ground. But a C2 or C3 crampon on a B1 boot has a binding that assumes a welt and a rigidity the boot does not have, so it can lever off. When in doubt, match the numbers (C1↔B1, C2↔B2, C3↔B3); if you cannot, go down the crampon scale, never up.

Choosing an ice axe

The good news after all that compatibility detail: an ice axe is simpler. For hillwalking you want one walking (mountaineering) axe — a long, fairly straight shaft with a gently curved pick, an adze on one side of the head and a spike at the base. Its jobs are support on the ascent, plunging into the snow like a stick, and, above all, self-arrest.

Length by height

Size it to your height. The fit test is quick: hold the axe by the head, arm relaxed at your side, and the spike at the bottom should reach roughly your ankle bone. As a rough guide by height:

Your heightWalking axe length
Around 5ft 2in / 157cm50–55cm
Around 5ft 6in / 168cm55–60cm
Around 5ft 10in / 178cm60–65cm
6ft / 183cm and over65–70cm

Most adults land in the 55–65cm band. Longer axes plunge more easily on gentle slopes; shorter axes are easier to wield on steep ground and in self-arrest. If you are between sizes, err slightly short — an over-long axe is awkward to bring round quickly when you need to stop a slide.

Walking axe, not a technical tool

Do not buy a curved climbing axe for hillwalking. A technical ice tool has a short, aggressively curved shaft, a steep, toothy pick and often a hand rest — brilliant for swinging into vertical ice, and poor for self-arrest and plunging. Under the current classification, a Type 1 axe is the basic mountaineering/walking rating (lighter shaft and pick, right for winter walking and glacier travel), while Type 2 is the technical rating (stronger pick and shaft for steep climbing). For winter hillwalking, a Type 1 straight-shafted walking axe is what you want. Aluminium axes are lighter and cheaper; steel axes are more durable and plunge better into hard neve — for Scotland's firm snow, a steel or steel-picked axe is the more reliable choice, with aluminium reserved for weight-critical ski touring.

Where to buy

Two rails worth using, and an honest note on each:

  • Amazon carries the mainstream axes and crampons (Grivel, Petzl, Black Diamond, DMM, CAMP) and is convenient, but you cannot try a crampon on your boot through a screen — and compatibility is the whole game here.
  • Tiso, the Scottish outdoor chain, and other specialists (Cotswold Outdoor, Go Outdoors, Needle Sports) let you take your boots in and have staff check the crampon actually fits and clips correctly. For your first crampon, do this — a ten-minute fitting in a shop is worth more than any spec sheet.

Frequently Asked Questions

What crampons do I need for my boots?

Match the crampon's C-rating to your boot's B-rating. B1 boots take C1 flexible crampons. B2 boots take C2 semi-automatic crampons, which clip onto the heel welt. B3 boots take C3 step-in crampons. The safe direction is to run a lower-rated crampon on a stiffer boot — a C1 on a B2 boot is fine — but never the reverse: a stiff C2 or C3 on a flexible boot can lever off on the hill. For general Scottish hillwalking, a B1 or B2 boot with a matching 12-point C1/C2 crampon covers almost everything.

Can you put crampons on normal walking boots?

Not proper mountaineering crampons. Flexible three-season boots are B0-rated and there is no C0 crampon — a rigid crampon on a bendy sole works loose and falls off, which on hard snow is dangerous. Flexible walking crampons or microspikes exist for softer boots on gentle frozen ground, but they are a lower-grade tool and no substitute for a 12-point crampon on steep snow. For any real winter hill, buy a B1 or B2 boot to go with the crampon.

What length ice axe do I need for hillwalking?

Most people want a walking axe of 55–65cm depending on height. Hold the axe by its head at your side and the spike should reach roughly your ankle bone. Taller walkers go towards 65–70cm, shorter walkers towards 50–55cm. Longer axes plunge more easily on gentle ground; shorter axes are easier to handle on steep terrain. If in doubt, err slightly short.

What is the difference between a walking ice axe and a technical ice axe?

A walking axe has a long, fairly straight shaft and a gently curved pick for plunging, support and smooth self-arrest — the right tool for hillwalking. A technical axe has a short, curved shaft, an aggressive pick and often a hand rest, built for swinging into steep ice. Technical tools are harder to self-arrest with and wrong for walking. For winter hillwalking you want a single straight-shafted walking axe.

Are aluminium or steel crampons better for Scotland?

Steel for almost everyone. Scottish winter ground is icy, rocky and abrasive, and steel points hold an edge and survive rock contact far better than aluminium. Aluminium is lighter and suits ski mountaineering and soft spring snow, but on Scotland's hard, mixed terrain it blunts and bends quickly. Buy steel 12-point crampons as your first and probably only pair.

How much should I spend on crampons and an ice axe?

Budget roughly £100–180 for a steel 12-point crampon and around £60–130 for a walking ice axe, with aluminium axes cheaper and steel dearer. Entry-level flexible walking crampons start around £80 but are a different tool. Prices move constantly and the retailers run winter sales, so treat these as bands and check the price on the day.
