As someone who has had very high arches all her life, I should have been wearing orthotic insoles from the beginning. But I wasn't. Only when I joined Tread Labs did I try on orthotic insoles and understand just what a difference they make in foot support. I found that the Stride's high arch model worked perfectly for me. My best friend is the complete opposite with extremely flat feet. She was shocked how much the Stride improved comfort. Howe could one insole provide optimal support for such different foot types? The answer is in the arch. No matter your arch height, there's an arch-supporting insole that can help both relieve and prevent many types of foot pain.
First, you need to know your arch height. If you don't already know, there's an easy way to find out.
The Footprint, Arch-Height Wet Test
Use this very easy footprint test to determine your arch height.
- Fill your tub with a small layer of water.
- Take two pieces of cardboard or heavy paper and set them on the floor.
- Step into the tub with one foot to wet the bottom of your foot.
- Lift up your foot and step onto one cardboard piece. Make sure to stand with your full weight on that one foot.
- Step off the cardboard and look down.
- Determine your arch height. If you see your entire footprint, you have a LOW arch. If you see half of your arch—like the typical "footprint in the sand" image—you have a MODERATE (normal) arch. If you see just your heel, the ball of your foot and almost none of your arch, you have a HIGH arch.
- Repeat steps 3 through 6 for the second foot to confirm that your arch heights are the same on both feet. If they aren't, you may need insoles of different arch heights, which Tread Labs can accommodate.

Determining your arch height is just the first step to understanding how insoles help each type of arch.
The Best Insoles for Flat Feet - How Arch Support Insoles Help
When you have flat feet, the entire bottom of your foot (the sole) touches the ground when you’re standing. Flat feet often occur when your arches don’t develop properly as you’re growing up or if you overpronate. They can also develop as you age or after a foot injury. For women, pregnancy can cause flat feet.
For some people, flat feet don’t cause any difficulties. But for others, they can cause:
- Pain in the heel (plantar fasciitis) or in the arch
- Swelling along the inside of your ankle
- Knee and hip problems
The best insoles for flat feet will fully support your arch and stabilize your heel to concentrate the fatty pad underneath your heel bone. This will both prevent overpronation and provide firm support. Typically, the best insoles for flat feet will have a low but supportive arch. However, you should try different heights to determine which one will adequately support your feet.
Moderate Arches — You Still Need Support
If your arch is neither low nor high, you have the most common foot type—moderate. Hooray, you're normal! But that doesn't mean you don't need arch support. In fact, it's the opposite. Your feet still need support to prevent overpronation. Plus, all feet benefit from support when you're exercising. Runners, walkers, and cyclists particularly need additional arch support.
High Arch — Support is Here
High arches are usually inherited and you have them from birth. If you develop a high arch in just one foot over the years or see just one high arch when you look at your footprint instead of two, please check with your doctor. The difference could be a neurological issue.
Typically, high arches alone don’t cause pain, but they can result in underpronation (more commonly known as supination). As a supinator, your arches don't collapse enough to absorb the shock of walking/running, which puts stress on your feet and can lead to:
- Plantar fasciitis
- Sore knees
- Sore hips
Insoles provide support for high arches and help prevent supination. Tread Labs Stride fully supports the arch and stabilizes the heel with a deep heel cup, which concentrates the fatty pad underneath your heel bone.
Note: If you have high arches, you may think that you need the highest possible insole, but you should try a couple of arch heights in your insoles to see which one will support your feet best.
