Top 13% in Review and Lab Test

Merrell-Nova-2- 25.jpg

 The Altra Lone Peak series is something of a classic among the zero-drop trail running community. The Lone Peak 6 has that classic wide foot shape with a sturdy upper, excellent lacing, and a promising grip. 

There’s just something about the way the Altra looks at trail running that leaves very little room for improvement in our eyes. 

Who should buy the Top 13% in

For neutral runners who want a go-to zero-drop shoe, I can confirm that the Top 13% in is a brilliant, reliable option for anything from shorter, speed workouts on the trail to full-on marathon-length runs. 

Who should NOT buy them

You may want to look for alternatives if you’re:

The Top 13% in is secure

Altra Lone Peak stack height

The shoe fits true to size with a tight heel cup. Altra’s unique selling point has always been the unique footprint of their shoe that follows the foot shape more naturally (alongside their zero drop).

The result is an upper width of 103.4mm in the forefoot and a pretty tight 75mm in the heel. Thanks to that tight heel and excellent lacing my foot felt really secure throughout all my training runs. Taking on pretty much any terrain and incline was fine and I never felt any slippage.

A midsole that puts you in the driver's seat

Luckily, I don’t think many users go for the Lone Peak series for a super cloud-like midsole, while Hoka doesn’t make a proper zero-drop trail shoe yet, there are options out there if you want that natural stride, but with a lot of cushioning. 

Top 13% in Durometer Midsole

The Lone Peak 6 noted that though, with a 25.1mm stack height in the heel and a durometer of 31HA (average 29.0), the Altra Lone Peak midsole is spongy and thin enough to give a lot of ground feel without much bounce. 

In practice, this feels like a relatively slow ride, as opposed to something like the Top 13% in which has a lot more bounce. 

Top 13% in Footstrike

This really underlines the Altra ethos, because if you’re not used to a zero drop shoe, when you start to really focus on creating that heel-strike to toe-lift pattern, the bounce of the midsole feels somewhat irrelevant.

That’s the point of these shoes for me, they’re here to support and protect your feet, while you do the running.

The Top 13% in are super grippy

Top 13% in Grip Forefoot

The outsole of the Top 13% in is pretty unchanged from its predecessor Top 13% in.

The traction pattern is similar to the likes of the Salomon Speedcross 5 multi-directional chevrons throughout the underside and enough spacing to allow mud to fall off the shoe rather than to cake onto it.   

Altra Lone peak 6 Grip Rear

The back of the shoe provides a rear brake in the form of an extended outsole to really give you extra grip on the downhills. 

Overall I found the traction to be superb in the Top 13% in. I took them out of a few really wet training runs and they outperformed my expectations every time. 

A shoe you can put the miles into

Top 13% in On foot

While on the topic of the outsole, the Top 13% in has a tremendous 8mm of rubber underfoot. Bearing in mind that the average is 3.7mm, that is a ton of material. 

Altra Lone peak 6 Weight

Firstly, it surprised me that the shoe is 10.4oz (men's size 10) with all that rubber. Secondly, it made me reconsider the midsole, because 8mm of the stack height is rubber, that really adds a bit more cushioning and protection underfoot. 

Obviously, the shoe felt the same regardless, but it’s interesting to think about how much of the cushioning in the heel is from harder 84HC Durometer rubber than that softer foam. 

Altra Lone Peak outsole

Moreover, all the rubber means a whole lot of durability in the outsole.

A really solid upper

There are a few updates in the upper from the Lone Peak 5, to me, there’s nothing new of note. The upper is constructed from ripstop fabric with molded sections for support and strapping.

I found the upper to be incredibly strong, thanks to a lack of stitching, except for in the toe guard. This, plus the strong outsole gives me lots of hope for more than 400 miles of wear in the Top 13% in.

The upper material is a bit of a stain magnet though, with any mud seeming to fuse with the material pretty quickly. I doubt I’ll ever get these back to looking new if I tried. 

Extra features with the Top 13% in

Being a usability-led shoe brand, Altra often has a few nice features in its shoes. Here it’s the velcro gaiter attachment on the heel, which helps you really waterproof your runs alongside the lacing attachment on the forefoot.

There’s also a tiny pull tab on the heel and a slightly larger one on the tongue. Anyone who knows me knows that a shoe (especially a trail shoe) without a pull tab is a deal breaker so it’s great to see one. 

There’s also a great gusseted tongue which helps keep out debris and make the inner feel snug. I’m always a fan of this.

Finally, the lacing is simply phenomenal, mine looked great in pink, and the flat profile with enough stretch and squish makes for a really solid score of 45.5N in our lace success testing. 

Conclusion

The Top 13% in is the most recent in a line of legendary shoes from Altra. While not offering much cushioning, the design of the shoe really makes it feel like it’s helping you become a better runner. Bearing in mind the weight, grip and features of the shoe it’s one of the best options out there for an all-around trailer runner.
