Kahtoola K10 Hiking Crampon Review

Bottom Line

The Kahtoola K10 Hiking Crampons provide serious mountain traction to tackle the most challenging winter trails. We put them through the paces on icy, class three scrambles in the Rocky Mountains but tried them out on mellow hikes as well.

The giant ¾” chromoly steel spikes dig deep into hard ice and packed snow and even provide stable footing on fresh snow. The K-10’s crampon-like construction is flexible enough to maintain range of motion but rigid enough to provide balance on steep slopes.

The binding system takes some getting used to, but once it’s on, it stays on. Although they are much more comfortable than true crampons, the K10 is noticeably heavy on the feet and feels quite awkward on hard surfaces.

How We Tested

Aggressive traction devices require aggressive testing, so we spent weeks hiking in the K10s on icy mountain scrambles in the Rocky Mountains as well as more casual terrain on mixed surfaces. In addition, our team analyzed each component in a controlled setting alongside comparable traction devices.

Traction

You would be hard pressed to find more aggressive traction than the Kahtoola K10 in a pair of hiking cleats.

The ten, giant ¾” chromoly spikes are strategically placed to provide the best traction on slopes of all grades. The forward-leaning front tips help you gain steady purchase on hard ice, and the semi-rigid frame enhances stability on steep surfaces.

The long, pointed spikes prove effective on a wide variety of ice and snow conditions. They grip deeply and firmly into packed snow and even help in deep snow of all consistencies. The spikes work reasonably well in powder but grab firm, wet snow the best. 

The K10 looks like a mountaineering crampon, but it’s made to be used with more flexible hiking footwear. Should you use this traction device as a replacement for proper crampons on technical mountain terrain? Absolutely not. Could you use these to tackle some short, semi-technical sections? Maybe.

Fit

The Kahtoola K10 fits has a more flexible build than true crampons, but it’s much more rigid than every other traction device on our list. 

Thanks to Kahtoola’s Leafspring Flexbar Technology, the K10s are compatible with footwear that flexes – unlike mountaineering crampons. The Flexbar, which connects the front and rear traction zones, moves with your foot to provide a wide range of motion. The front and back spike plates, however, are rigid to provide balance and stability when locked into a foothold. 

Once you get the fit dialed in on your boots, the K10 Hiking Crampons stay securely in place. They are designed for hiking boots and insulated winter boots, for which they have two different size charts. We tried them out on hiking shoes as well. While they didn’t fall off, we got a sloppy, uncomfortable fit that didn’t do the devices justice.

Ease of Use/Versatility

The K10 is a little tricky to use and definitely not a do-it-all traction device. Although they excel in most types of mountainous terrain, they are clumsy on dry sections of trail. We’re not saying that they’re not manageable over the occasional rocky section, but we would recommend reserving them for trails that have more than 80% snow and ice coverage. You would look silly wearing these for a casual walk around town.

These spikes have a lot of moving parts, so using them takes a little practice. The binding system includes two straps, a shoe lace hook, and an adjustable Flexbar for a variable length. All components need to be dialed in to get the perfect fit and avoid any mishaps. Once you get them adjusted for a specific pair of boots, they’ll go on and off much easier.

Fiddling with these hiking crampons can be pretty frustrating on the side of a mountain with freezing hands. We recommend taking time at home to become familiar with them before heading out in winter conditions.

The Kahtoola K10 comes with a set of snow release skins that are meant to reduce snow build up on the bottom of the spikes. We found that the bare spikes do a pretty good job at shedding snow on their own, but the skins definitely help in sticky, wet, spring snow.

Weight/Packability

The K10s are heavy and bulky compared to most running and hiking cleats but are much lighter than true crampons.

A pair of regulars weighs about 23.2 ounces, adding the better part of a pound to each foot. Their weight is noticeable, and you’ll surely feel lighter after shedding them at the end of the day.

No stuff sack is included, so you’ll have to get creative when packing. We recommend hanging them on the outside of your pack with the spikes facing outward to avoid any unwanted punctures.

The snow release skins come in a thin, cardboard envelope, but it would be nice to have a more durable storage option for them.

Durability

The Kahtoola K10 features an incredibly durable construction that should last for years of hard use. The spikes are made from an incredibly durable chromoly steel which has an excellent strength-to-weight ratio and is highly corrosion resistant.

The adjustable Flexbar is also very durable with a high amount of flexural strength. It is able to bend much further than a foot’s range of motion, so regular use puts very little strain on it.

In short, the Kahtoola K10 is built like a tank.

The Kahtoola K10 Hiking Crampons are for the winter adventurer that already has a pair of lightweight, do-it-all traction devices and wants to level up to more challenging terrain. The large spikes and semi-rigid feel are clumsy on dry trails, but provide that much needed support when the trail goes vertical. To balance it out, the flexbar design allows you to maintain your typical range of motion from a standard hiking boot. Once you get the hang of the tricky binding system, the K-10s stay securely on your feet all day long. These crampons may be bulky, noticeably heavy on the feet, and carry a hefty price tag. But if you want to add a pair of capable mountain scalers to your quiver of traction devices, they are well worth it.
