WHY FIT MATTERS:

Choose Support Based on Your Unique Biomechanics

Everyone’s feet are different. Choosing insoles based on guesswork or shoe size alone can lead to discomfort, reduced performance, and even increased stress on your knees, hips, and back.

By measuring your arch profile and knee alignment at home, you’ll get a personalized starting point for choosing the best insoles for your body and activity.

The easiest way to measure your arch at home is with the Wet Foot Test, a quick and accurate method to determine whether your arch is High, Medium, or Low.

TIPS »

Compare your footprint to the arch types below and note the letter assigned.

A

High Arch

You’ll see a very narrow band, or no connection at all, between the ball and heel, indicating minimal arch contact.

B

Medium Arch

A distinct curve along the inside of your foot is visible, but the ball and heel remain connected.

Angled Out

Your knees angle away from each other.

Frequently Asked Questions

Find answers to common arch testing and fit questions

What if I get different results on different days?

Your arch profile can vary slightly depending on activity and time of day. If in doubt, use the lower arch result, as it typically provides better support and comfort.

Can I do the test wearing socks?

Thin socks are fine, but barefoot is best for accuracy.

What if I pick the wrong arch type?

Our insoles are designed to adapt to your foot’s movement, but selecting the right profile ensures the best performance. If you’re unsure, retest or see one of the experts at the stores that carry CURREX for confirmation.

What if my footprint doesn’t clearly match any arch type?
  • Try the pencil test as a secondary method.
  • Retest after light activity or later in the day, when feet are slightly more flexible.
  • If still uncertain, choose the lower of two possible arch types—this usually leads to a better fit.
What if my left and right footprints are different?

This is common. Choose insoles based on the lower arch if there’s a noticeable difference. You can also consult a professional or use an in-store ArchMap™ scanner for confirmation.

Can I redo the test?

Yes. In fact, rechecking every 6–12 months is smart. Your arch height and alignment can shift over time or with changes in activity levels.
