Brooks Men 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 ?

3. Prepare a soapy solution

Mix lukewarm water with a bit of mild soap.

4. Clean the shoes

Dip a cloth or a soft brush in the soapy water and gently scrub the dirty areas.
For the soles, use a stiffer brush if necessary.

5. Rinse with a damp cloth

Wipe the shoes with a clean, slightly damp cloth to remove the soap.

Stuff the shoes with newspaper to absorb moisture and help them retain their shape.
Let them air dry away from direct heat sources (radiator, sunlight).
