Nike InfinityRN 4 Blueprint multicolor/multicolor women's running shoes (HJ6649-900)

Women's Running Shoes Nike InfinityRN 4 Blueprint are designed for daily running training and maximum user comfort. High cushioning provided by ReactX foam in the midsole enables soft landings and dynamic take-offs. The cradle-shaped platform structure promotes fluid movement, while the waterproof membrane protects against moisture during runs in challenging weather conditions.

Advanced ReactX Technology

The Nike InfinityRN 4 Blueprint women's running shoes utilise ReactX foam, developed to enhance cushioning and improve energy return. This makes each step more responsive and reduces joint strain. The cradle shape in the midsole facilitates a natural transition from heel to toe, supporting prolonged and stable running.

Comfortable Upper Construction

The Nike InfinityRN 4 Blueprint women's running shoes feature an improved Flyknit upper that provides appropriate flexibility and breathability. The widened forefoot area ensures comfort while running, especially over longer distances. The soft collar and anatomically shaped tongue wrap around the foot, enhancing stability during dynamic movements.

Traction and Durability of the Outsole

The Nike InfinityRN 4 Blueprint women's running shoes are equipped with a waffle-patterned outsole that ensures secure contact with asphalt surfaces. The tread structure increases traction during acceleration and braking. The durability of the rubber used means the shoes are suitable for intensive use on hard surfaces.

Protection Against Weather Conditions

The Nike InfinityRN 4 Blueprint women's running shoes offer a waterproof membrane that effectively isolates the interior from moisture. This keeps the foot dry even when running in the rain or on wet surfaces. This solution provides greater comfort and hygiene during regular training sessions in variable weather conditions.

    How to measure the length of your foot - instructions in 4 steps

    1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

    2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

    3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

    4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
