361° Karios 2 ($140)
Introduction
The Kairos 2 is an “inherent stability” trainer. By inherent we mean that instead of firmer foam posts or plastic support pieces it relies on its platform width, geometry and outsole rubber for its stability and support. It sits in the rapidly emerging more inherent stability category with shoes such as the ASICS Gel-Kayano 30 and Nimbus 26 and Puma ForeverRun Nitro compared at the end of the review.
It has 361’s excellent lively Engage TPE foam which we first experienced in the more neutral but still quite stable Centauri late in 2022 (RTR Review)
