Size guide - Women

At ECCO we are committed to make your online shopping experience as easy as possible. The best way to make sure that you order the right size is to measure your feet and then compare it with the size chart below to find the appropriate size. Please follow these 4 simple steps to accurately measure your feet:

  • All your need to measure your feet from heel to toe is a piece of paper, a pencil and a ruler.

  • Place the paper on the floor up against a wall. Place the heel against the wall.

  • Mark the longest part of your foot on the paper. Repeat procedure with the other foot.

  • Measure the length of each mark and match it with the size chart. Let the longest foot decide the shoe size.

    <small>BIOM® NATURAL MOTION®</small>


    BIOM® NATURAL MOTION® technology is based on the natural shape and movement of the foot. It encourages the muscles and ligaments in your leg and foot to strengthen with every step — making your movements more efficient and smooth, and allowing for a more powerful push-off. BIOM’s key elements are reduced seam construction, an anatomical last which is designed to match the curves of your foot, low-to-the-ground construction, and easy flexibility. These features create an embracing glove-like fit that frees you to move with barefoot ease and efficiency.
