As with the racing model, the TRI-WRAP BOA structure is further improved with the ZG series features a significantly improved concept that is significantly stronger and faster. The new midsole, upper and outsole common to the ZG23 series are inherited as well (See race model description for details). The TRI-WRAP panels are thinner and lighter but have improved material strength with a filament material that has been made even lighter than the previous BOA model and has improved stability and a sense of hold. Structurally divided into the main panel and top panel, the new top panel automatically adjusts to the instep height and shape of the foot for stability and fit in the optimal position.
