What’s the Caldera 8 all about?
The Brooks Caldera is back for its eighth iteration and while it’s not a complete overhaul, it’s a thoughtful refinement of an already great shoe. At first glance, it might seem like just an upper update, but small details go a long way—especially in a shoe designed with ultrarunners in mind.
I appreciate that Brooks listened to feedback from the previous version, making only necessary changes while retaining what worked. Too often, brands alter things unnecessarily, frustrating loyal users. In this case, Brooks has smartly kept the winning formula intact. The Caldera 8 still features the nitrogen-infused DNA Loft v3 foam, delivering comfort from mile one to mile 100. The updates make this shoe more durable, comfortable, breathable and sustainable.
There's three key changes in Caldera 8:
1) Dialed fit, secure lockdown
The fit, materials and overall comfort have been improved based on feedback from the Caldera 7. The updated upper is made from TPEE (thermoplastic polyester elastomer), which is both hydrophobic and abrasion-resistant. This makes it repel water, be more durable, breathable and quick-drying.
The shoe provides a secure midfoot and heel lockdown, giving you confidence on technical terrain, while the relatively generous toe box offers extra volume for those who need it. This is a positive change that enhances overall comfort.
2) Caldera goes Carbon Neutral
To achieve carbon-neutral certification, Brooks increased the use of recycled materials to reduce emissions and support carbon offset projects to neutralize the remaining impact. As a trail runner, this is a fantastic step forward. Running in nature makes us more aware of our environmental footprint, and it’s encouraging to see brands taking responsibility for sustainability.
3) Small tweaks make for a premium feel
As mentioned earlier, this version is more of a refinement than a full redesign, but a few small details make the Caldera 8 stand out in the market.
Heel Pull Tab: Personally I love when shoes have a pull tab—it’s a small touch that makes a big difference, especially in the middle of an ultra race when you're tired and having to swap socks out. However, the Velcro gaiter tab from the previous version has been removed in version 8.
TPU Toecap: One of my favourite things about Brooks trail shoes is that they are sturdy and protective and while the toecap does its job well, I found it slightly too rigid, which caused my big toenail to rub against it. If you're sensitive to this, you might consider going half a size up.
Padded, Perforated Tongue: The tongue has been updated with extra padding and perforations to enhance comfort and airflow. This helps prevent pressure points while keeping the foot cool and dry over long distances.
Our first thoughts
The Caldera 8 remains Brooks' max-cushion trail shoe, designed for ultramarathons. While it’s not as soft as you might expect given the amount of foam, the flex grooves in the outsole provide adaptability to the terrain. This results in a smooth, stable ride that balances protection, comfort, and reliability. For us, the Caldera sits alongside shoes like the Hoka Speedgoat 6, Salomon Ultra Glide 3 and Asics Trabuco Max 4.
Best suited for long days on the trail, ultra races, or hiking, I could also see myself choosing this shoe for rogaining, or adventure racing. If you’re looking for a well-cushioned, long-distance trail shoe with smart refinements, the Caldera 8 is worth considering.

Seb Lopez - Trail Runner & Photographer
I’m passionate about trail running, hiking, adventure racing, and the outdoors in general. My favourite runs are long days spent with mates, exploring new places.
I also appreciate how different shoes allow me to connect with the terrain in unique ways and how that affects the running experience. When I’m not out on the trails, you’ll probably find me behind the camera as a sports photographer. It’s great to be on the other side and see the sport from a different angle.
