Reviewing the Mammut Sertig II: A Closer Look at Trail-Ready Footwear

While we’ve seen a few reviews of Mammut products in the past, this marks my first, as well as Run Oregon’s, review of Mammut shoes. Our recent trial involved the Mammut Sertig II Low, a pair from their ‘everyday’ line.

Design and Appearance

This shoe has a fun appearance, blending classic design with unique details, like a playful, almost leopard-print pattern on the outer. While blue and black aren’t my usual favorites, they’re not off-putting either. Mammut offers several other color options in this style that look equally appealing. Plus, the outsole design stands out as particularly unique.

It’s somewhat intriguing because they resemble a trail shoe and are suitable for such use, but the outsole seems more geared for hiking. As such, Mammut rates them 6/6 for hiking and 5/6 for ‘fast hiking,’ (which is the yaboyscottjurek definition of ultraunning I think). Thus, it’s curious to find them categorized in the Everyday lineup as opposed to Trail Running or Hiking. For what its worth there is Trail Running version of the Sertig (the Sertig TR) that may provide a little more trail running capacity.

Fit & Construction

These shoes may not be ideal for those with wide feet. Despite not needing wide sizes myself, I found the midfoot area a bit snug. Walking around, I felt the insole brushing against the inner part of my foot, prompting me to opt for thicker socks.

As a runner, I found Mammut’s 5/6 cushioning score somewhat generous. Comparing it to plush running shoes I’ve used, I’d rate the cushioning of the Sertig II closer to a 3.5/6. The EVA midsole provides decent bounce, but there’s noticeable groundfeel. Perhaps I have just been accustomed to the road running cushion that most of us are looking for, but it’s no Hoka Mach 6 or Asics Superblast.

The mesh upper offers good breathability, although the shoe – seemingly with an eye for hiking – prioritizes durability and structure (and quick drying) over extreme breathability. It strikes a balance that favors longevity over maximum airflow, catering more to those who prioritize durability on the trails. The outsole is impressively solid and grippy, a standout feature of the shoe.

Overall

This hasn’t been our favorite trail shoe we have recently reviewed, but it’s still a nice and affordable option (currently priced at $101) for someone that truly does want an option that doesn’t necessitate usage only for running miles on the trail. For something that caters to thinner feet, and can be a comfortable option for hiking and even wearing out and about, this fits the bill quite well.
