The JOLT 4 shoe is designed to help you run or walk more comfortably. This shoe combines an Amplifoam midsole with a solid rubber outsole for added durability. Inspired by our durable GT series, this sneaker offers classic style and a great fit. To make this edition even softer and adapt better to your foot while running. We have incorporated several flex grooves into the outsole. The upper is reinforced by stitched overlays. Finally, a more comfortable fit in the forefoot area and a soft Ortholite insole ensure you feel comfortable all day long.
