Hillsound Traction Devices: The Full Lineup Compared
Hillsound builds the more aggressive version of everything Kahtoola makes, usually at a similar price. Longer spikes, spikes mounted on rigid steel plates instead of dangling from free chain, and on several models a velcro over-strap across the instep that stops the harness rotating under load. The design brief is visible in the products: these are for people whose winter trails tilt, freeze hard and get polished to glass by traffic.
That character has a cost. Hillsound devices are heavier, bulkier in a pack, harsher on bare ground and slower to fit with cold hands. If your winter is rolling trail and the odd icy patch, the extra length is weight you carry and clatter you hear without ever cashing in the grip. The lineup below runs from everyday to genuinely steep.
| Model | Spikes per foot | Spike length | Weight (pair) | Over-strap | Role |
|---|---|---|---|---|---|
| FreeSteps6 | 6 | Short, everyday profile | ~350 g | No | Sidewalks, commutes, packed snow around town |
| Trail Crampon Ultra | ~18, short profile | ~12–15 mm | ~380 g | Not on most versions | Rolling to moderate icy trail |
| Trail Crampon | 11 | ~17 mm | ~490 g | Yes | Steep, hard, polished trail ice |
| Trail Crampon Pro | ~10 | ~20 mm | ~650 g | Yes | Deep firm snowpack, steep winter approaches |
Figures are approximate catalog values for medium sizes and change between production runs. Hillsound also sells the Armadillo gaiter range alongside the traction line, which pairs naturally with the longer-spiked models on snowy trails. Confirm current specs and the size chart on the listing before ordering.
The decoder: length, plates and the strap
Three things separate one Hillsound from the next, and none of them is the model name.
Spike length is the terrain limit. Around 12–15 mm on the Ultra bites into hard-frozen ground and packed snow while staying manageable on short bare sections. The Trail Crampon's ~17 mm punches through a boot-polished crust into the softer layer underneath, which on a 25-degree frozen descent is the difference between placing every step and simply walking. The Pro's much longer points are for firm snowpack deep enough that a trail-length spike rides on top and skids — a rung most winter hikers never need.
The plate chassis is the quiet Hillsound advantage. Spikes sit on steel plates under the forefoot and heel rather than hanging on free chain, so each spike has a rigid base to push against instead of pivoting on a link. Edging across a sidehill, the forefoot plate keeps the outer spikes engaged rather than letting the array roll under your arch. It is also why the Ultra grips more like a trail crampon than a microspike despite similar weight.
The velcro over-strap solves harness migration. Elastomer harnesses creep on steep descents and repeated toe-off until the spikes are no longer centred under the sole. The strap stops that and gives you a second point of retention if the harness tears. Snug is the setting, not crushing — over-tightening on an insulated boot restricts circulation.
Hillsound sizing, and how it differs from Kahtoola
Sizing is the top buyer question in this category and the most common reason a good device disappoints. Two rules cover most of it.
First, size to the boot, not to your street shoe size. The harness wraps an outsole, and an insulated winter boot carries noticeably more footprint than a trail runner in the same nominal size. Read the chart against the number on the boot box, using the bulkiest footwear you expect to pair the device with.
Second, do not assume your Kahtoola size carries over. Both brands sell S/M/L/XL bands keyed to shoe size, but the bands are drawn differently and the harnesses stretch differently, so the same boot can land in different letters. Check Hillsound's current chart for the exact model you are buying rather than reproducing a size from memory — bands also differ between the Ultra, the Trail Crampon and the Pro.
Between sizes, go up for bulky insulated boots and down for low hikers and runners. A harness that has to stretch to seat is a harness that stays put; one that slips on easily in a warm room will be sloppy at -15 °C when the elastomer stiffens. Tolerance is tightest on the Ultra, which has no strap to compensate for a harness that is slightly loose.
Fit check at home on carpet, not at a dark trailhead: spikes centred under the sole, heel cup fully seated behind the heel, no elastomer bunched under the arch, no fore-aft slide when you push the toe of the device by hand.
Which Hillsound for which person
- One device for mixed winter days: Trail Crampon Ultra. Microspike weight, plate-chassis grip, and light enough that it actually stays in the pack all season.
- Steep, polished, refrozen descents with a loaded pack: Trail Crampon. The over-strap and ~17 mm spikes are worth the extra weight if that is your standard day.
- Deep firm snowpack on steep winter trails: Trail Crampon Pro — the same envelope as a flexible hiking crampon, and only after you have found the limit of shorter spikes on ground you already travel.
- Sidewalks, driveways and the commute: FreeSteps6, or a bead-style device. Compare the whole everyday category in our ice cleats for walking roundup.
- Winter running: none of them. Plates and long spikes fight a running cadence, and a low-profile carbide device is the right tool.
Cross-shopping Kahtoola
These two brands are compared more than any other pair in winter traction, and the honest split is about slope rather than quality. Kahtoola MICROspikes run 12 stainless spikes at ~10.4 mm for ~340 g a pair, with no over-strap, and they roll into a jacket pocket. The Hillsound Trail Crampon runs 11 carbon-steel spikes at ~17 mm for ~490 g with a strap, and does not pack flat.
MICROspikes win on weight, packability and comfort across long mixed days, and they are the better first purchase for moderate trails. The Trail Crampon wins on outright bite and on security when the ground tilts, particularly on descents. The full head-to-head is in MICROspikes vs Hillsound, and the wider field is ranked in best microspikes of 2026.
None of these is a crampon. The name on the box says crampon; the device is a trail traction system. No front points, no rigid frame, no attachment to a boot welt, and a sole underneath that bends. Once a slope is steep enough that a slip would slide rather than stop — steep snowfields, alpine gullies, icy scrambles, anything glaciated — the equipment changes entirely: boots stiff enough to hold a real crampon, a 12-point steel crampon, an ice axe, and practised self-arrest. If you are unsure which side of that line your plan sits on, read when do you need crampons and microspikes vs crampons first.

FAQ
Which Hillsound should I buy first?
The Trail Crampon Ultra for most winter hikers — it covers rolling and moderately icy trail at a weight you will carry every time. Move up to the Trail Crampon if your regular descents are steep, sustained and polished, which is the one case where the extra spike length and the strap clearly pay for themselves.
Is my Kahtoola size the same in Hillsound?
Not reliably. Both use S/M/L/XL bands keyed to shoe size, but the bands and the harness stretch differ, so the same boot can fall in a different letter. Check the current chart for the specific Hillsound model against the boot you will wear, and go up rather than down if you are between bands on insulated footwear.
Do Hillsound spikes rust?
The carbon steel used on the Trail Crampon will rust if the pair is thrown wet into a pack and forgotten. Rinse road salt off, dry them fully at room temperature and store them loose. Surface rust on the spikes is cosmetic; rust at the chain links is worth inspecting before a season.
Can I wear them on pavement?
For short connecting stretches. Long spikes on asphalt are loud, unstable underfoot and blunt faster, and the Trail Crampon and Pro are unpleasant over any distance on bare ground. If most of your winter is paved, buy FreeSteps6 or a bead-style cleat instead.
