Microspikes

Also called traction devices, spikes

What are microspikes?

Microspikes are elastomer harnesses with short chains and spikes, roughly 10 to 15 mm, that stretch over a shoe for traction on packed snow and ice. They are the middle rung between yaktrax-style coils and full crampons, and they are not mountaineering equipment.

Where they work

Packed snow, frozen trail, icy boardwalk and the hard refrozen surface that a popular winter trail turns into. On that ground they transform a slithering, nervous walk into a normal one, and they take about fifteen seconds to put on. For a huge amount of shoulder season and winter day hiking they are the single most useful thing in the pack.

They are also fine on moderate slopes where a slip means sitting down rather than sliding somewhere. The spikes are short and the harness is elastic, so what they give you is grip on a surface, not the ability to stand on a steep face.

Where you need something else

On steep, hard alpine ice, on any slope where a slide would not stop, or anywhere you would want to swing an axe, microspikes are the wrong tool and the short points will not hold. That is crampon terrain, with a rigid or semi-rigid boot to mount them on and an ice axe to go with them.

The gap between the two is where people get hurt, because a trail that starts as packed snow can steepen into a genuine slide risk without any obvious transition. The honest question is what happens if your feet go, and if the answer is that you do not stop, microspikes are not the answer.

Fit and care

Sizing is by shoe size and the elastomer needs to be under real tension, so a harness that goes on easily is probably too big and will roll off in deep snow. Rinse and dry them after use because the chains rust, and carry them in their own bag unless you want the spikes finding your sleeping pad.

What this means when you're choosing

  • Stainless chain and spikes, since these live wet and rust otherwise
  • A snug fit under real tension, because a loose harness rolls off in deep snow
  • A carry bag, unless you enjoy finding holes in things
  • Whether your route actually stays moderate, or steepens into crampon ground

Which to pick: Microspikes for winter and shoulder-season trail. Crampons and an axe the moment a fall would keep going, which is a decision to make before you are standing on it.

The common mistake

Taking them somewhere that needs crampons

Short spikes on an elastic harness grip a surface. They do not let you stand on steep hard ice, and they will not hold a slip on a slope that keeps going. If a fall would not stop on its own, that is crampon and ice axe terrain regardless of how well the microspikes worked lower down.

Common questions

What is the difference between microspikes and crampons?

Spike length and how they mount. Microspikes are 10 to 15 mm points on an elastic harness that pulls over any shoe, for packed snow and ice. Crampons have much longer points and bind rigidly to a stiff boot, for steep alpine ice.

Can I wear microspikes on trail running shoes?

Yes, and plenty of people do for winter running. Check the size range covers your shoe, and accept that a soft shoe gives you less to push against than a boot does.

Do microspikes help in deep snow?

Not much. They grip a hard surface, and deep unconsolidated snow has none. That is snowshoe territory, and postholing is what happens without them.

Lug depth

Lugs are the raised blocks on the sole of a boot or trail shoe, and lug depth is how tall they are, usually 3 to 6 mm. Deeper lugs bite into soft ground; shallower ones give more contact area on rock and hard trail.

Outsole

The outsole is the rubber layer on the bottom of a shoe, the part touching the ground. It carries the lug pattern and the rubber compound, which together decide grip, and it's usually the first part of a shoe to wear out visibly.

Midsole

The midsole is the foam layer between the outsole and your foot. It absorbs impact and sets how stiff or soft a shoe feels, and it's the part that quietly dies long before the tread looks worn.

EVA foam

EVA is the light, springy foam most hiking and running midsoles are made of. It cushions well and weighs little, but it compresses permanently over time, which is why shoes go flat after a few hundred miles.

Stack height

Stack height is how much material sits between your foot and the ground, measured in millimetres at the heel and forefoot. More stack means more cushioning and less ground feel; less means more feedback and a lower, more stable platform.

Heel-to-toe drop

Drop is the height difference between a shoe's heel stack and its forefoot stack, given in millimetres. Zero drop means the foot sits level; 8 to 12 mm tilts you forward slightly and shortens the load on the calf and Achilles.

Rock plate

A rock plate is a thin stiff sheet, usually TPU or a nylon composite, embedded in the forefoot of a shoe. It spreads the load from a sharp rock across the whole foot instead of letting it press into one point.

Shank

A shank is a stiffening insert running through the arch of a boot, made of steel, nylon or composite. It controls how much the boot twists and bends, which is what lets a boot support a heavy load and edge on rock.

Rand

A rand is a strip of rubber bonded around the lower edge of a boot's upper, most often at the toe. It takes the abrasion from rock and roots that would otherwise wear through fabric or leather, and it protects your toes from impact.

Gusseted tongue

A gusseted tongue is sewn to the sides of the boot with fabric panels instead of hanging free. It seals the gap along the laces so grit and water can't get in, and it stops the tongue sliding sideways as you walk.

Vibram Megagrip

Megagrip is a Vibram rubber compound formulated for grip on wet and dry rock. It's softer and stickier than standard hiking rubber, which is why it holds on slabs and greasy roots, and why it wears out faster.

Gaiters

Gaiters are fabric sleeves worn over the top of a shoe or boot to keep grit, snow and water out. Low trail gaiters cover the collar and stop scree filling your shoes; tall gaiters run to the knee and seal the leg against deep snow and wet brush.

Crampon

A crampon is a metal frame carrying 10 or more points up to 5 cm long that binds rigidly to a stiff-soled boot, so a climber can stand on hard alpine ice and steep snow. It is the tier above microspikes, and it is technical equipment that needs an ice axe and training.

Insulation weight in grams

Insulation weight is the mass in grams of one square meter of the insulating sheet inside a boot or glove. A 400g boot uses a heavier sheet than a 200g boot, so it is warmer, but it is nothing like twice as warm.

Vibram Arctic Grip

Arctic Grip is a Vibram outsole technology built for traction on wet ice. It stays pliable at temperatures where ordinary hiking rubber goes hard, which is the reason a winter sole grips where a three season one skates.

Flotation

Flotation is how well a snowshoe keeps you on top of snow instead of sinking into it. It is a function of deck surface area measured against your loaded weight, which is your body plus clothing, boots and everything in your pack.

Heel lift

A heel lift is a small wire or plastic bar behind the heel of a snowshoe that flips up so your boot rests on it during a climb. It stops your calf being held at full stretch on sustained steep ground.
