    Despite not being much of a zero drop fan, the Paradigm 1.5 felt amazing with Hoka like cushioning, very low weight and a fast and responsive feel.

    lyweight, maximum cushioning without sacrificing stability.

  • 80 / 100 | Fueled by LOLz | | Level 4 expert

    I don’t notice the difference in the heel to toe drop and I like the high cushion in the shoe. 

  • 75 / 100 | Fueled by LOLz | | Level 4 expert

    In conclusion, I do think they are a good shoe for me. I was pleasantly surprised with how much I do like them!

  • 85 / 100 | Ultrarunner Podcast | | Level 3 expert

    I'd recommend them as post-run shoes, as their slipper-like fit feels great after a tough day on the trails.

    The unaggressive tread—wide, shallow lugs and deeper grooves—worked well on mixed-terrain runs that alternated between pavement, dirt and gravel roads and dry, mellow singletrack.

  • The Altra Paradigm 1.5 made a major update in its upper unit. The upper totally came out in a newer design with durability features. It was designed to give increased breathability and comfort. The toe-box is wide for toe splay and it has new reflective overlays for increased visibility.

The Paradigm 1.5 has a standard running shoe size. This shoe is not ideal for the narrow-footed runners since the forefoot area was a wider compared to its predecessor. However, the heel and midfoot maintains the standard measurements. This shoe is available in standard widths of D for the men’s and B for the women’s.


The outsole unit of the Paradigm 1.5 features the FootPod outsole that follows the natural foot construction, offering an enhanced flexibility and responsive ride. This outsole design is also used in other Altra running shoes, such as the Paradigm 4.


The Altra Paradigm 1.5 uses the Dual Layer EVA with A-Bound Top Layer technology that provides a lightweight, durable cushioning and flexible underfoot protection. Runners will experience a protected and relaxed foot strike with these combining technologies.

It also uses the brand’s Natural Ride System that is engineered to allow the foot to move naturally and aids the natural mechanisms of the foot for a much comfortable and improved running performance.


The upper part uses the Quick-Dry Air Mesh, keeping the foot well-ventilated. It also has a moisture-wicking capacity to keep the foot dry, cool and odorless.

For a more secure fit and comfortable feel, by following the natural foot shape of the runners, the Altra Paradigm 1.5 utilizes the brand’s Asymmetrical Lacing Design system.

Lastly, the updated version of the shoe has new reflective overlays that cover around the upper unit to increase visibility especially when running on low light conditions.
