SIZING: For the best fit, choose the same size as your current running shoes assuming you have a full thumb’s width of space from your longest toe to the shoe’s end; Newtons run true to athletic sizing, but if you're between sizes, go with the larger one for optimal comfort.
SUPERIOR CUSHIONING AND COMFORT: The Newton Running Lady Isaac 2 features next-gen NRG Plus and Hytrel foams, providing unmatched cushioning to minimize impact and enhance comfort for both long runs and casual wear.
ENHANCED PERFORMANCE AND ENERGY RETURN: With Split-Lug Action Reaction Technology, the Isaac 2 offers a softer, smoother ride by compressing 8 independent flex-lugs into the midsole, acting like a trampoline to maximize rebound and energy return with each stride.
INNOVATIVE DESIGN FOR FORWARD MOMENTUM: Sculpted rocker geometry amplifies forward momentum and reduces weight, making the Isaac 2 an amazingly soft yet versatile shoe that keeps you moving efficiently.
ADAPTIVE AND BREATHABLE UPPER: Crafted with seamless Adaptive-Fit Air Mesh, the upper molds to your foot shape, allowing for optimal airflow. Features like an anatomically designed air mesh and perforated tongue enhance breathability and comfort.
CUSTOMIZED FIT AND COMFORT: The multi-positional lacing system, plush anti-friction linings, and Hytrel foam footbed provide a secure, personalized fit, making the Newton Running Lady Isaac 2 feel like it was built just for you.
