Updates to Altra Olympus 2.5

  • The Olympus 2.5 by Altra features a few minor updates. The most obvious one was made to its upper. Compared to its predecessor, the upper of the Olympus 2.5 is more reinforced, with a different mesh material that offers better durability. This type of mesh material doesn’t expand as much compared to the mesh material on the previous version of this shoe.
  • The overall style has also been revamped to give the shoe a more contemporary feel in terms of design. There is still the expression of colors found on the overlays and on the midsole. However, the color accents have been slightly muted, so the design of the shoe feels more cohesive.
  • Altra retained the maximum thickness of its sole unit to maintain the reputation of the Olympus series as Altra's most cushioned footwear. This level of cushioning still does the job of protecting the foot and when running on the trail.

Altra Olympus 2.5 size and fit

The Olympus 2.5 comes in standard shoe sizes. Runners will be able to enjoy the shoe in their regular size preferences. Despite this, some retailers suggest purchasing half-a-size larger than usual to get the best fit.

In terms of width, runners will be able to get the shoe in standard width measurements. Males can avail of the shoe in D – Medium width, while females can get the shoe in B – Medium width.


The Altra Olympus 2.5 retains its durable lugged Vibram MegaGrip Outsole. This robust component is suitable for trail running and other outdoor activities that need a shoe that offers reliable traction on both dry and wet terrain. Durability is also a key feature of the outsole, as it is made up of a high-performance rubber compound.

The shape of the outsole is more foot-like. The tread pattern found on the upper portion of the outsole mimics the shape of the toes, while the lower portion’s tread pattern gives way to proper foot mechanics and natural movement.


The midsole is made up of a special blend of materials – first is the A-Bound technology and next is the dual-layer EVA. The environmentally friendly A-Bound was developed by recycling various materials, making the compound more resilient to wear and tear. This gives enough protection to the underfoot of the shoe. On the other hand, the dual EVA layer adds more cushioning to the shoe to deliver comfort and a more efficient ride to runners.

The midsole follows the natural foot-shaped scheme of the platform, enhancing the runner’s experience with every stride. This type of design works together with the rest of the elements of the shoe to enhance comfort and movement.


The upper sports an abrasion-resistant mesh with minimal seams. Despite the upper material being anti-wear and tear, it still maintains its breathability, allowing air to pass through the tiny holes in the mesh. This reduces hot spots and makes the inside of the shoe cooler during runs.

Various overlays found on the lateral sides of the shoe, the toe tip, and the heel help retain the shoe’s shape, giving the shoe some lightweight support and protection. The overlay on the toe tip protects this part of the shoe from tearing as this is one area which is prone to abrasion when running on the trail.

Altra made sure the trail running gaiters incorporate seamlessly into the shoe’s system. To make this happen, the 4-Point Gaiter Trap Technology was introduced. This design is basically a set of add-ons – the Velcro strap on the heel, the loop at the base of the lacing system, and the two laces that show up on the collar portion of the shoe. They allow trail running gaiters to be securely fastened.
