The Racing All-Rounder 

The lightweight design of the adizero adios 8, in combination with a low profile and responsive midsole, is made for a direct and snappy feeling in races or speed workouts.


Featuring LIGHTSTRIKE PRO foam in the forefoot and LIGHTSTRIKE 2.0 in the heel and midfoot gives a cushioned landing and a dynamic spring feeling.

Lightweight Mesh Upper

The all-new upper construction of the Adios 8 is stripped back, making it the lightest adios ever.


The updated ENERGYTORSION ROD 2.0 is embedded in the midsole with a new third rod that runs through the midfoot to the forefoot for a snappy toe-off in each stride.

Everyday Mileage Shoes

Everyday mileage running shoes provide comfort and support for daily training sessions, ensuring endurance and durability. These shoes are designed to withstand the wear and tear of frequent use, offering reliability and performance for your regular runs.

Tempo Running Shoes

Tempo running shoes are engineered for speed and agility, optimizing performance during high-intensity workouts. With lightweight construction and responsive cushioning, these shoes excel during your tempo runs, helping runners maintain pace and efficiency.

Race Day Shoes

Race day running shoes are crafted for maximum speed and efficiency, designed to propel you towards their personal bests. These lightweight and minimalist shoes prioritize agility and responsiveness, ensuring every stride counts on the big day.

Why Should You Have a Shoe Rotation?
Rotating running shoes can extend the life of each pair by allowing them to fully dry out and have foam rebound between runs, reducing wear and tear, and potentially lowering the risk of injury by changing the stress your body goes through when running in different models.

Merrell Womens MTL Skyfire

Find extra speed on extreme trails in the Merrell Women’s MTL Skyfire. Stripped down, and race ready they combine responsive foam with mountain grade Quantum grip lugs to keep you moving over everything.
The mesh upper on the Merrell Women’ s MTL Skyfire is tear resistant, lightweight and breathable so that you can take it through any terrain at pace. TPU overlays improve durability and offer support. A responsive EVA midsole offers cushioning that will keep you moving, while a rock plate adds further underfoot protection. The mountain grade Quantum grip rubber outsole is designed to find traction on steep slopes and varying terrain.


Boasting a stripped-down, lightweight design that’s ideal for racing, the Merrell Skyfire is equipped for the mountains with responsive foam and trail-ready protection. It can take on technical terrains as well as paved roads and excels at shorter distances.

Regular Cushioning

Regular cushioning offers a blend of lightness, comfort, and ground feel. Popular for shorter distance racing as well as training and daily mileage running, the lower stack of midsole foam offers inherent stability and a lighter feel on your foot when compared to max-stack shoes.


Neutral running shoes are designed to provide a smooth sensation without correcting your gait. They allow your natural motion to flow, while still offering a snug fit and a cushioned feel underfoot. As such, they’re ideal for runners who don’t overpronate.


Merrell built an excellent reputation with their hiking boots, and the obvious step into trail running has borne fruit.

Whether you’re ultra-racing, want a bit of protection across rocky trails, looking for a hybrid trail and road shoe, or after an agile lightweight off-road racer, Merrell are the perfect choice for your next outdoor adventure.

Off-Road Running

Take to the trails and leave the urban landscape behind in our off-road shoes.

Designed to offer traction across all kinds of terrain, from rocks and roots to mud and grass, they often feature small blunt spikes called “lugs” to dig into softer ground.

Many also feature improved protection in the upper, keeping loose rocks and branches at bay.

Best for Severe Trail

Trail shoes can come with many levels of protection, lightness, and cushioning, but the main thing that differentiates between severe and light trail is the outsole traction. Severe trail shoes tend to have deep lugs to offer improved grip in wet mud and loose gravel, letting you sprint over the most technical of terrain with total confidence.
