Nike Air Zoom Tempo NEXT% Flyknit Fast Pack Sneakers - Black - UK 10

Place your foot on a flat surface with your heel against a wall. Measure from the wall to the tip of your longest toe. It's best to do this in the afternoon when feet may be slightly swollen. Compare this measurement in centimeters (cm) to the 'Foot Length (cm)' column in the size chart.

The Air Zoom technology provides responsive cushioning, meaning it compresses on impact and then quickly springs back, offering a propulsive and energetic feel during your run.

Yes, Flyknit is designed to be both lightweight and durable. It offers a supportive structure that holds up well to the demands of regular training sessions.

Re-measure your foot length carefully from heel to toe and compare it against the provided size chart. If between sizes, consider ordering the next size up. Foot length can vary slightly throughout the day; measure in the afternoon or evening for best results.

Ensure the laces are not over-tightened. Loosen them and re-lace, focusing on even pressure. The Flyknit material is designed to be snug; allow a few runs for it to adapt to your foot shape.

Ensure the shoes are not excessively worn. Check the midsole for signs of compression. Clean the outsole to ensure optimal grip and performance. Consistent use on abrasive surfaces can impact longevity.

Clean the outsole thoroughly to remove any debris that may be affecting grip. Note that wet surfaces inherently reduce traction for most running shoes; exercise caution.
