The Altra Torin 8 is a notable zero-drop running shoe, best suited for runners seeking a barefoot experience. It provides significant ground feel, an actual zero drop, and a fluid midsole, all validated by lab tests. Additionally, its foot-shaped toebox enhances comfort during off-road activities.
Two key factors contribute to the Torin 8's barely-there feel: its flat profile and adaptive midsole. With a heel drop measuring just -0.1 mm, it offers a genuine zero-drop experience. The platform's fluid motion complements movements seamlessly, confirmed by our bend test, which shows it is 6.7% more flexible than average.
Another reason for its agility is the exceptional ground feel, provided by a minimal 27.6/27.7 mm stack height. The high level of surface feedback allows adaptation to various terrains, demonstrated by its below-average shock absorption score of 110 SA in the heel.
Our measurements of the gel mold replica indicate ample room in the toebox, with a caliper confirming a width of 83.6 mm. This measurement indicates it is 13.7% wider than average, making it spacious enough for those with broad feet.
A drawback of the Altra Torin 8 is its limited ventilation, which may be a concern for warmer conditions. Runners who prioritize breathability should consider alternative options.

Constructed with EGO MAX foam, the VIA Olympus 2 delivers a generously cushioned and responsive experience that enhances comfort during endurance runs. The shoe features a tall 34.8 mm heel and a 35.0 mm forefoot, marking it as one of the tallest in its category, while maintaining a 0.2 mm drop to align with Altra’s zero-drop philosophy. Its plush foam is 32.2% softer than average, providing each stride with notable bounce and comfort.
The toebox incorporates Altra’s FootShape design, replicating the natural foot silhouette for enhanced comfort. With a roomy 104.4 mm toebox that tapers to 91.1 mm at the big toe, it effectively accommodates foot swelling experienced during long runs.
Additionally, the outsole utilizes FootPod technology, featuring anatomical cuts that align with the foot structure. Although it has a softer composition compared to typical models, it exhibits 33.3% less wear in our Dremel test than average, demonstrating its durability.
A noted drawback of the VIA Olympus 2 is its limited ventilation, which may lead to blisters and hotspots during runs in hot conditions. If breathability is essential for your activities, you may want to consider alternative options.
