Kahtoola MICROspikes Ghost Review

Overview

The MICROspikes Ghost is Kahtoola’s ultralight reboot of its category-defining MICROspikes, swapping the steel chain matrix for a TPU webbing to cut weight nearly in half. It’s aimed squarely at trail runners, thru-hikers, and anyone in soft-soled trail runners who wants real ice traction without the clunky feel of the original chain-based design — it’s a winter traction aid optimized for use with trail runners that have a soft sole and a collapsible toe box.

Performance

The headline feature is obviously the weight cut. Kahtoola replaced the standard stainless steel chain with a TPU matrix, and reviewers consistently clock the Ghost at 43% lighter than the original MICROspikes traction, with the TPU matrix designed to cut bulk without compromising strength. On paper that’s the difference between roughly 12 oz and 6.8 oz per pair for a size medium — meaningful if you’re carrying these “just in case” for a shoulder-season ridge crossing.

Traction itself doesn’t feel like a big compromise despite the shorter spikes. One long-term tester who ran the Ghost through multiple winters in the Boulder foothills found that the Ghost has proven to be exceptionally durable and provide essentially the same traction as the regular Microspikes despite the spikes being slightly shorter. The same review notes the spikes measure .36” vs. .41” compared to the standard MICROspikes — about 10% shorter, which lines up with SectionHiker’s measurement that the spikes on the Ghost are about 10% shorter than those on original Microspikes. In practice, most testers say that difference disappears on the trail; RoadTrailRun’s reviewer put it bluntly: most users will find that difference imperceptible.

Where the Ghost really separates itself is fit and comfort with trail runners — the whole reason it exists. Anyone who’s tried cramming original MICROspikes onto a soft-soled shoe knows the pain point: SectionHiker describes it as feeling like you’re walking on nails and that someone is stepping on your toes, both at the same time, because Kahtoola’s original Microspikes work best with footwear, usually boots, that have a thicker sole and a rigid toe box. The Ghost fixes this with a softer, more articulated harness — Treeline’s tester noted the flexible TPU harness and articulated rivets allow the 12 metal spikes to move with the shoe rather than fighting it. SectionHiker’s bottom line after testing both: the Ghost balances comfort and performance well for day hikes on icy and packed trails, and is far more comfortable than wearing Kahtoola’s original Microspikes.

That flexibility comes from a deliberate rivet design — Backpacker’s reviewer explains that the Ghost gets its flexibility from stainless steel rivets that allow each section of TPU and stainless steel spike cluster to pivot underfoot, which is what keeps the harness from twisting and stops snow from balling up underfoot during longer efforts.

Against the wider ultralight traction field, the Ghost comes out well ahead on the tooth-length-to-weight ratio. Backpacker’s comparison is useful here: the Snowline Chainsen Trail Light comes in at 7.1 ounces per pair, with roughly 5-millimeter teeth — not particularly useful in sloppy conditions, while Black Diamond’s Distance Spike weighs 8 ounces per pair with nearly 8mm teeth — better than Chainsen’s Trail Light, but not as robust as the Ghost. In other words, the Ghost is both lighter and longer-toothed than its closest direct competitors — a fairly rare combination.

Durability is the one open question given how new this product is. Kahtoola backs it with the same coverage as the rest of the line — MICROspikes Ghost footwear traction is backed by a 4-year limited warranty, warrantied to the original owner and replaced or repaired at Kahtoola’s discretion — which suggests the company is confident in the TPU matrix holding up. But with less metal per spike cluster, don’t expect infinite mileage on abrasive rock: as RoadTrailRun’s long-term tester notes, the wear rate/durability of the spikes is the same, but with less metal, they do run out a little bit quicker.

One fit note worth flagging for deep snow: Outdoor Prolink’s tester recommends they’re best paired with boots or well-sealed footwear in deeper snow — the low-profile harness that makes these so comfortable on hardpack doesn’t do much to keep snow out of a mesh trail runner.

Pros & Cons

Pros

• Roughly half the weight of standard MICROspikes with comparable real-world traction
• Far more comfortable on soft-soled trail runners — no more “walking on nails” toe-box pinch
• Articulated TPU/rivet design flexes naturally with the shoe and resists snow buildup
• Packs down to a tiny stuff sack — easy “just in case” item for shoulder-season trips
• Backed by Kahtoola’s standard 4-year warranty
• Longer spikes than most direct ultralight competitors (Chainsen Trail Light, BD Distance Spike)

Cons

• Spikes are shorter than the original MICROspikes, so it’s a step down for sustained, steep, or sustained hardpack ice travel
• Less metal per spike cluster means faster wear over the long haul, per long-term testers
• Not ideal for deep, loose snow with mesh trail runners — better matched to boots or sealed footwear in those conditions
• New enough to the market that multi-season durability data is still thin

Who Should Buy This

The Ghost is built for trail runners, fastpackers, and thru-hikers doing shoulder-season miles in trail runners who need occasional traction on icy or hardpacked sections but don’t want a heavy, boot-oriented device riding in the pack for 95% of the trip. If you’re doing sustained mountaineering-adjacent travel on steep, consistent ice, the original MICROspikes (or a proper crampon) is still the better tool — the Ghost trades some raw bite and long-term spike life for weight and trail-runner comfort.

Verdict

Kahtoola took its best-known product, cut the weight nearly in half, and didn’t gut the traction that made the original a category leader — that’s a hard needle to thread, and by most tester accounts they pulled it off. It’s not a replacement for the standard MICROspikes on serious ice, but for the shoulder-season “just in case” traction that most thru-hikers and trail runners actually need, the Ghost is the new default. I’d put it at an 8.3/10.
