The verdict

Is the Altra Lone Peak 9 worth it?

Yes, if your toes feel cramped in ordinary trail shoes. The Lone Peak 9 has a roomy, foot-shaped toe box, a flat zero-drop platform and moderate cushioning on a grippy MaxTrac sole. The catch is the zero drop, which loads your calves and Achilles more and takes a few weeks to adapt to.

That mix is why it is the shoe we point wide-footed runners and long-distance hikers to in our trail running shoe ranking. The roomy forefoot matters most late in a long day, when feet swell and a tapered shoe starts to rub.

It is not the grippiest shoe on wet rock, and the 25 mm stack is moderate rather than plush. If you have never worn a zero-drop shoe, build up slowly with short runs before taking it on a long trip.

Buy it if

  • Wide forefeet, bunions or toes that want to spread
  • Long days and thru-hikes where feet swell
  • Runners and hikers already used to low-drop shoes
  • Mixed trail where you want moderate, all-round grip

Skip it if

  • You have narrow feet and like a locked-down fit
  • You have never worn zero drop and have a trip coming up soon
  • You need maximum grip on wet rock or deep mud

From Altra Running's published specs.

What's good

  • A forefoot roomy enough for toes to splay under load
  • Comfortable on long days when narrower shoes start to pinch
  • StoneGuard insert takes the sting out of sharp rocks
  • Built-in tab makes adding a trail gaiter simple

What to know

  • Zero drop needs weeks of adaptation for most people
  • Grip is good rather than exceptional on wet, smooth rock
  • Wide fit can feel sloppy on narrow feet in technical terrain

How does the Altra Lone Peak 9 fit?

Roomy in the forefoot and normal through the heel. Altra's Original FootShape is its widest toe box, shaped like a foot rather than a point, so your toes can spread out as they land. Most buyers find it true to length.

If your feet are narrow, the extra room can let your foot shift on side slopes. Snugging the laces through the midfoot helps, but a narrower shoe may suit you better.

What does zero drop mean for the Lone Peak 9?

Your heel and forefoot sit at the same height, so there is no raised heel. That encourages a midfoot landing, but it also stretches your calves and Achilles more than a typical trail shoe with 8 to 10 mm of drop. Start with short runs and walks, and add distance over several weeks.

Is the Lone Peak 9 good for hiking?

Yes, and it is one of the most common shoes on long trails like the Appalachian and Pacific Crest Trails. It is light, dries faster than a boot, and the wide toe box handles swelling over many miles. With a heavy pack, some hikers want more cushioning or support underfoot.

Questions

Altra Lone Peak 9 FAQ

Does the Altra Lone Peak 9 run true to size?

Most buyers say it runs true to length. Because the toe box is already wide, there is rarely a reason to size up for width.

Is the Lone Peak 9 waterproof?

The standard version is not. It has a breathable mesh upper that drains and dries quickly. Altra sells a Gore-Tex version for wet, cold conditions, which runs a bit heavier and warmer.

What is the difference between the Lone Peak 9 and the Lone Peak 9+?

The 9+ swaps the MaxTrac outsole for a Vibram Megagrip sole, which grips better on wet rock. The fit and zero-drop platform are the same.

How long does it take to get used to zero drop?

Many runners need a few weeks. Mix short runs in the Lone Peak with your old shoes, and back off if your calves or Achilles stay sore the next day.
