Altra Olympus 6 vs Inov-8 TrailFly Ultra G 300 MAX

The Altra Olympus 6 is the stronger pick for most trail runners. It pairs a 33mm max-cushion midsole with a Vibram Megagrip outsole and Altra's roomiest Original FootShape toe box, and owners rate it 4.8 out of 5. The inov-8 TrailFly Ultra G 300 MAX is a lighter, lower-profile option with a 6mm drop and graphene-enhanced grip, but it comes in medium width only and its round toe gives toes less room. Choose the Altra for long, technical trail days and wide feet; choose the inov-8 if you prefer a traditional drop and a snugger fit.

  • Choose the Altra Olympus 6 if you want maximum cushioning, a wide foot-shaped toe box and proven Vibram grip for long trail runs and hikes.
  • Choose the inov-8 TrailFly Ultra G 300 MAX if you prefer a 6mm heel drop, a lighter shoe and a medium-width fit closer to a standard running shoe.

What reviewers say

Altra Olympus 6

Questions and answers

Which is better for a first 50-mile trail race?
The Altra Olympus 6. Its 33mm max cushion and roomy toe box protect feet over long miles, and Vibram Megagrip handles wet descents. The inov-8 works for shorter or less technical courses.
Which lasts longer?
The Altra Olympus 6. Its Vibram Megagrip outsole and updated lug pattern are built for durability on long ultras. The inov-8's lighter build wears faster on rocky ground.
Is the inov-8 worth stepping up to over the Altra?
Only if you want a lighter shoe with a 6mm drop. The Altra offers more cushioning, a wider toe box and stronger grip, so most trail runners get more from it.
Which suits wide feet?
The Altra Olympus 6. Its Original FootShape is Altra's roomiest toe box with space through the midfoot. The inov-8 comes in medium width only.
Which is better for hiking as well as running?
The Altra Olympus 6. Altra lists it for hiking and all-day trail use, and the max cushion and grip suit long days on foot. The inov-8 is tuned more narrowly for trail running.
Does the zero drop of the Altra take getting used to?
Yes. Moving from a 6mm drop like the inov-8 to 0mm shifts load to your calves and Achilles, so build mileage gradually.
