The NOVABLAST™ 5 SUNNY SIZZLE running shoe's midsole and outsole geometry helps produce an energized ride. FF BLAST™ MAX cushioning helps create softer landings and a more energized toe-off during your training. A tongue wing construction in the upper helps improve the fit while reducing tongue movement. Collection Inspiration: Part of the SUNNY SIZZLE Collection, this pack is inspired by the colors you'd see while running at sunrise or sunset (golden hour). It also features a lightweight sublimated upper mesh that's specifically designed for keeping your feet cool and comfortable while running in the spring and summer seasons. A unique gradient spray also appears on the upper and midsole to complement the golden hour color influences.
