Testing Context

Our favorite time of year to hike is during the winter, and I have thousands of miles of hiking under my belt wearing spike-style traction devices of one sort or another. I come from a mountaineering background, so I’m pretty in tune with the performance of any type of traction device that helps me quickly and safely cross snow and ice. Through the years, I’ve accumulated an embarrassingly large amount of crampons and traction spikes suitable for ice climbing, trail running, and everything in between. And I discuss traction devices and their appropriate use as matched to the terrain in our recent webinar Lightweight Footwear and Traction Systems for Snow Travel.

I tested the Black Diamond Blitz Spikes on a number of trips in the mountains of Southeast Wyoming and Northern Colorado during the winter and spring months. I spent most of my time on packed snow trails, transitioning to mixed terrain (snow/water ice/dirt) as spring rolled around. As of this review, I have about 50 miles of experience with them while carrying an overnight backpack (20 to 40 lb / 9 to 18 kg) over terrain with slope angles of up to about 25 degrees.

I paired the Black Diamond Blitz Spikes with the following footwear:

Most often, I would wear the Blitz on one foot and another traction device on the other, so I could make direct comparisons. The comparison devices were usually the Black Diamond Distance Spikes, the Kahtoola Microspikes, or the Hillsound Trail Crampons.

This is a first look at new gear that recently entered our review pipeline, and hasn't yet been subjected to rigorous field use. Learn more about the types of product reviews we publish.

First Impressions

Small Size

The most notable feature of the Black Diamond Blitz Spikes is their diminutive size. They are so small and light that I wouldn’t give a second thought about tossing them in my pack for the just-in-case scenario of having to inch my way over a snowy, moderately steep mountain pass during early season summer travel.

The Black Diamond Blitz Spikes are the first traction device I’ve used that I literally stuffed into my pants and jacket pockets, or my front accessory pack. They are so small that you have multiple storage options when not in use.

Short Spikes

The individual spikes on the Blitz are 8 mm long. They seem tiny compared to the 12 mm long spikes on Kahtoola Microspikes. Shorter spikes have two important impacts that are noticeable in the field:

  1. When wearing them on bare ground (e.g., dirt) and moving fast, my forefoot caught on the terrain underneath far less often than when I was wearing Kahtoola Microspikes. This is a big advantage, especially for trail running or at the end of the day when my legs are tired and my coordination is compromised.
  2. When climbing (and descending) steep, snowy (or muddy) terrain, the short spikes of the Blitz don’t have as much purchase (grip) as the Kahtoola Microspikes. If you have to rely on a totally secure grip on steep terrain where a fall is an issue, you may need a more aggressive traction device than the Blitz.

Ease of Use

Two straps – a nylon toe strap (webbing) and an elastomer heel strap – make these the easiest set of traction spikes to put on and take off my shoes that I’ve ever used. A nice-sized grab loop in the back makes the process intuitive and easy.

Footwear Applicability

The Blitz performs best (and perhaps, most sensibly) when mated to ultralight footwear. I had no issues when I used them with my Hoka Speedgoat trail running shoes and Speedgoat GTX mid-height boots. When I paired them with my stiffer approach shoes (the Scarpa Zen Pro II), the fit was secure and the spikes remained stable on the shoe even on steep terrain. However, when I paired them with a stiffer mountain boot (Scarpa Marmolada), the boot seemed to overpower the Blitz Spikes, causing them to shift position on the sole of the boot while sidehilling on steep terrain.

Paired with an approach shoe, the Black Diamond Blitz Spikes are ideal for short crossings of glaciers or snowfields prior to rocky scrambling on higher peaks.

On my Inov-8 G270’s, the Black Diamond Blitz Spikes’ front strap digs a little into the top of the shoe, because the shoe top is quite soft. It didn’t cause any notable discomfort, but be aware of this when you are matching traction spikes like this to minimalist footwear.

On a high-stack shoe like the Hoka Speedgoat, or if you’re attaching them to boots, you may need to size up, so the rear elastic band doesn’t get caught underfoot and wear unnecessarily while walking.

The Black Diamond Blitz Spikes only have six spikes under the forefoot, which limits their use to low-angle snow if you need to walk a sidehill traverse.

The Takeaway

Tiny size, truly ultralight, and speed (ease) of taking them off and putting them on are the hallmark features of the Black Diamond Blitz Spikes. I imagine they will remain in my ultralight backpacking kit for mountain travel until the snow melts out of the high passes, and I plan to use them for most of my trips this year in the Colorado Rockies and High Sierra.
