Nike Women Shoes

First of all, don’t measure your feet in the morning. They often swell during the day because of the heat and your activity. To choose the right size, measure your foot at the end of the day.

To measure your shoe size, follow these instructions:

  1. Place a sheet of paper on the floor against a wall.
  2. Stand on the paper with your heel against the wall.
  3. Mark the point where your toes stop with a pencil.

Then measure the distance between the tip of the paper and the mark you’ve made, and compare it with our size chart.

IN BETWEEN SIZES?

  • For tight fit, go one size down.
  • For loose fit, go one size up.

How to care ?

Before Washing

✔ Turn clothes inside out → This helps protect the fabric and preserve prints or logos.
✔ Check the labels → Some fabrics require special care.
✔ Shake off dirt → Especially for hiking clothes, remove mud and debris before washing.

Washing Instructions

1. Use cold or lukewarm water (30°C max)

  • Hot water can damage synthetic fibers and elastic materials.

2. Choose a mild detergent

  • Avoid fabric softeners, as they can clog breathable materials and reduce moisture-wicking properties.
  • Prefer liquid detergent over powder to prevent residue buildup.

3. Use a gentle wash cycle

  • A delicate or sportswear program is ideal.
  • Do not overload the machine to allow proper rinsing.

4. Hand wash if needed

  • For delicate items (compression wear, technical fabrics), soak in lukewarm water with a bit of detergent, then rinse thoroughly.

Drying Instructions

Air dry whenever possible

→ Hang clothes in a well-ventilated area.

Avoid direct sunlight

→ It may weaken the fabric and fade colors.

Do not use a tumble dryer

→ High heat can shrink or damage sportswear elasticity.

Extra Tips:

  • Remove odors naturally → Add white vinegar (½ cup) or baking soda (1 tablespoon) to the wash.
  • Wash sportswear separately → Avoid mixing with cotton clothes, which can transfer lint.
  • Never leave sweaty clothes in the laundry basket for too long → Wash as soon as possible to prevent bacteria buildup.
