Choose MICROspikes when the walking part of your route is predominantly packed snow or persistent ice on a hiking trail. Choose EXOspikes when a moderate route repeatedly shifts among icy path, exposed rock, bare trail and pavement. Neither name alone settles the choice: check the exact shoe or boot against Kahtoola’s separate charts and reject a device that will not stay correctly seated.
This is a comparison of published product design, sizing and use limits, checked on 30 September 2026. We have not worn either pair or measured traction. The decision below is a way to match a documented design to a route, not a promise that one grips better in every condition.
Start with the surface that dominates your walk
| Your likely route | Better starting point | Why, and where the inference stops |
|---|---|---|
| Mostly continuous packed snow and icy hiking trail | MICROspikes | Kahtoola positions its 10.4 mm chain-linked steel spikes for mountain trails and stubborn ice. This does not establish safe footing on every slope. |
| Moderate winter trail with frequent bare patches, rock or paved approach | EXOspikes | Kahtoola designed the 7.4 mm carbide-tipped TPU matrix for road-to-trail transitions. It still has metal points, so bare hard surfaces demand care. |
| Mostly dry pavement with only a short icy section | Reassess whether either should stay on throughout | The route has little continuous snow or ice. Plan where to put traction on and take it off rather than assuming spikes belong on every surface. |
| Steep, exposed terrain where a slip has serious consequences | Check route conditions and required equipment before choosing | Neither stretch-on device is a mountaineering crampon or a substitute for appropriate skills and route judgment. |
These are use-case matches from Kahtoola’s MICROspikes specification , EXOspikes specification and traction range comparison . Spike length and material describe construction; they do not provide a controlled head-to-head grip result. Ice texture, snow cover, slope and underlying rock can all change the practical decision. If the forecast or trail report is uncertain, choose a route whose consequences you can manage.
What you are actually carrying
MICROspikes have 12 steel points per foot, each 0.41 in / 10.4 mm long, on welded chains. Listed pair weights run from 285 g in XS to 422 g in XXL. The deeper chain-linked design explains the icy-trail match; it does not measure point penetration or prove grip on your route.
EXOspikes also have 12 points per foot, using 0.29 in / 7.4 mm carbide tips in a flexible TPU matrix. Listed pair weights run from 188 to 230 g across XS to XL. Kahtoola positions this design for road-to-trail travel. That supports the mixed-surface match, without proving how long it lasts on dry pavement or whether it outlasts MICROspikes in your use.
The published weight ranges do not overlap, but the gap for your footwear depends on the sizes that actually fit. Do not subtract the XS weight of one product from the XL weight of the other to make a personal weight-saving claim. Compare the weight of the size that fits your footwear, and let route and fit take priority over a few ounces in a pack.
Size the device to the footwear, not just your foot
The charts apply to different footwear categories. Kahtoola gives MICROspikes one chart for hiking shoes and boots and another for insulated boots. Its EXOspikes chart is for trail-running and hiking shoes. An insulated winter boot that fits your foot at the same labeled shoe size may have a bulkier outer shape, so it cannot simply inherit your trail shoe’s traction size.
For a concrete example, a men’s US 9.5 hiking shoe falls in M on the MICROspikes hiking-shoe chart and M on the EXOspikes trail-shoe chart. A men’s US 9.5 insulated boot falls in L on the separate MICROspikes boot chart. The same labeled footwear size can therefore lead to a different traction size. An EXOspikes letter cannot be inferred for that insulated boot because its published chart addresses trail-running and hiking shoes. Size boundaries and unusual footwear shapes still require a physical fit check.
Use this order before purchase:
- Identify the actual footwear you will wear, including the model and whether it is an insulated boot. If you are still choosing shoes, the site’s hiking shoe fit comparison explains why heel hold and toe room come first.
- Open the appropriate sizing section on the MICROspikes page or EXOspikes page . Both charts are approximate, and Kahtoola says bulky, narrow or irregular footwear may need adjustment, particularly at a boundary.
- Before the trip, install both devices on the footwear you will use. Confirm the front and rear are seated, the harness is centered and the points sit under the sole. Walk on a safe surface and check for twisting, slipping or a toe that pushes through.
- If the device feels excessively strained or will not stay seated, do not treat the size chart as proof of fit. Resolve the fit with a dealer or a return while the product is still eligible.
Kahtoola’s EXOspikes user manual requires correct size and a secure fit before use. It also directs inspection for missing or damaged points, cracks, cuts and bent links. The current product pages direct users to inspect the devices before use, clean them with lukewarm water, air-dry them and remove them from footwear between uses.
A purchase choice you can use at the trailhead
If your trail report describes a long frozen tread and you will wear hiking boots, start with MICROspikes and its boot-specific sizing chart. If your normal walk begins on a plowed street, crosses repeated exposed ground and only intermittently meets ice, start with EXOspikes and its trail-shoe chart. A route that changes from pavement to a solid icy climb may justify carrying traction until the icy section rather than choosing solely for the approach.
Do not confuse traction with debris or weather protection. If snow or grit is entering a low shoe, the site’s INSTAgaiter Low versus Mid guide addresses coverage. If friction develops under a fitted harness, pause and address the shoe fit; the blister-care guide is for managing a hot spot, not making an unstable traction device acceptable.
Once you know your route and footwear, check MICROspikes sizes on Amazon for a sustained icy trail, or check EXOspikes sizes on Amazon for a mixed road-to-trail route. The linked product identities were checked, but each listing may open on a different size. Current stock is unknown. Confirm model, size, seller terms, price and availability before paying.
The limit that matters most
The manufacturer’s EXOspikes manual says this type of added traction is for pedestrian use, not mountaineering, and cannot prevent every slip or fall. Apply that caution to the choice as a whole: stretch-on points are not mountaineering crampons, and no grip is guaranteed. When the route is too steep, exposed or uncertain for your skill and equipment, change the route or get qualified local advice before going.
