Performance and comfort meet in the Speedsland GS:TAM, a highly cushioned, high-performance trail running shoe suitable for even the longest and most winding trails. Lightweight and durable, GS:TAM ensures excellent performance thanks to the application of fiberlite technology developed exclusively by JV International. In fact, this technology consists in the insertion of a thin fabric inside the reinforced sole, giving flexibility and lightness to the sole. GS:TAM is a fully customizable model, starting with its sole and continuing with the presence of a Carbitex GearFlex carbon fiber plate, compatible with all Speedland models. Even the design of the lugs can be customized through a very simple operation of “cutting” the individual lugs to fit the actual needs of the individual runner.
