Gel-Nimbus 10.1The Gel Nimbus 10. 1, derived from the 2008 version, maintains its emphasis on comfort. Familiar elements from the late 2000s, such as the asymmetrical upper and unique open mesh feature, are reintroduced. These elements were specifically incorporated to accommodate the natural structure of the foot. Additionally, the dual layer EVA foam, GEL technology inserts, and TRUSSTIC system in the midsole deliver exceptional cushioning and support.
