Product information

Altra EGO™ MAX

The updated midsole in the Altra EGO™ MAX is designed to combine soft cushioning with a stable feel on technical surfaces.

The cushioning provides protection during long runs and helps smooth out hard impacts from rocks, gravel and roots. The high sole platform is especially suitable when comfort and protection are prioritized over maximum ground feel.

Vibram® Megagrip with TractionLug™

The Vibram® Megagrip outsole provides reliable contact on both wet and dry surfaces. TractionLug™ complements the rubber compound with a dual lug design that improves grip and stability on technical terrain.

The outsole works well on:

Rocky mountain paths

Wet and dry rock outcrops

Forest trails

Roots

Packed soil

Gravel roads

Mixed trail surfaces

MATRYX® upper

The upper is made from a continuous woven MATRYX® material . The construction provides a durable and supportive upper for long distances and technical terrain.

The material helps keep the foot in place through the midfoot, which is especially important on steep climbs, fast descents and uneven terrain.

Original FootShape™

The Olympus 275 HiLo uses the Original FootShape™ , Altra's roomiest fit.

The wider shape gives your toes room to spread out while keeping your foot stable through the midfoot. This is especially appreciated during long runs and ultra races, when feet can swell.

Original FootShape™ means a spacious and anatomically shaped toe box. It is not the same as a traditional wide size.

0 mm drop

The shoe has as much material under the heel as under the forefoot, which gives 0 mm drop .

If you are used to running shoes with a higher drop, you should get used to the model gradually:

Start with shorter and calmer sessions.

Vary your regular running shoes.

Increase distance and altitude gradually.

Wait with really long sessions until your body has gotten used to it.

Always test the shoes thoroughly before competing.

Place your heel lightly against the wall.

Mark the longest toe.
