[Featured in our Best Trail Running Shoes Guide]

The Altra Lone Peak 4.5 is the latest edition of Altra’s original trail running shoe, and it’s the best yet.

Altra trimmed down the new model for improved flexibility and comfort without compromising the shoe’s classic fit and feel.

Designers embedded a StoneGuard rock plate into the midsole for lightweight protection against jagged rocks and roots, and multi-directional outsole lugs give you superior grip on unpredictable trails.

A 25 mm stack height provides ample cushion for a comfortable ride, so you can tackle any trail with confidence.

Solid trail runner

So far, so good. The Lone Peak 4.5 seems to have the same traction and toe room as previous models, and felt good right out of the box. Time will tell about durability. A bit pricey but previously I've felt it was worth it to get the extra toe room in this shoe. Truly foot-shaped :)

Running and hiking shoes

I recently bought some running shoes and hiking shoes from Fleet Feet. Their staff is always knowledgeable and thoughtful. I have many issues with my feet and Fleet Feet always recommend shoes which work for me. Thank you!!

Great customer service and care

I had my shoes shipped and they were stolen from my doorstep. Fleet Feet were exceptionally understanding and quick to replace my shoes. I was not just thankful but awed by the exceptional customer care.
