# Breathable Trail Sneakers Salomon ACS Pro Shell Adds Open Mesh Construction in New Colorways By Amy Duong | Published 2026-03-26 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/acs-pro-shell References: [salomon](http://salomon.com/)  The ACS Pro Shell by [Salomon](https://www.trendhunter.com/trends/acoldwall-x-salomon-acs-pro) expands the ACS Pro line with a reworked upper focused on airflow and reduced weight. French outdoor brand Salomon introduces two new colorways, “Rainy Day/Black/Castlerock” and a tonal “Black” version, built on the same technical silhouette. The shoe features an open mesh structure with cut-out windows and a lightweight cage, designed to increase breathability while maintaining support through the brand’s Agile Chassis System. The model retains core ACS Pro elements including Quicklace fastening, Contagrip outsole, and a synthetic-textile upper layered for durability. The revised construction shifts the silhouette toward warm-weather wear, with airflow prioritized across the upper through 3D mesh and exposed sections. Both versions include sculpted midsoles and technical overlays consistent with the original design language.
