The GEL-FOUNDATION 13 over the years has been a sought after model for providing a highly stable and supportive ride. The tooling carries SpEva Foam and Solyte Midsole whilst the upper has been refined to further improve the fit and overall running experience. Utilising a more contemporary design, the consumer now has a fresh take on a shoe in this category. Key updates include a modified fit over the Forefoot (wider and higher) that provides more room with a Bunion Window on the medial side. Additionally, a new SpEva Sockliner has been added to provide further comfort.
