How To Measure Your Feet

Wear socks similar to ones you’ll be wearing with the shoes. While seated, put your foot on a piece of paper in front of you and trace around the circumference of it with a pencil, being careful to keep the pencil close to the foot.


To determine your foot length, measure the distance between the two furthest points on your tracing.


Observe the table above and find the measurement closest to your foot length. Choose the shoe size attributed to that length.

  • Soft Primeknit covers the upper of this Ultra Boost
  • That knitted material extends high across the ankle, keeping the foot securely locked in place
  • A rigid lace surround features in the same shade of grey as the upper whilst rope laces fasten in a similar construct to a walking shoe.
  • As an All-Terrain shoe, this pair is made even more robust with an embossed lace surround, hidden beneath the Primeknit
  • A chunky 3D printed overlay sits across the heel which continues the theme in a deep shade of grey.
  • That chunky Boost midsole is finished off with a deep tread outsole, engineered to offer protection across all surfaces.
