MEET GROUNDFORM

Not Something You Wear. Something You Train On.

A pair of soft silicone foot trainers, one for each foot. Your toes sit between four posts on a textured top.

Three moves. That's the whole idea.

01

SPREAD

Do: Slot your toes between the posts and let them spread.

Uses: Four toe posts, big toe on the open outer edge.

Trains: Toe position and control.

02

GRIP

Do: Curl and press your toes down, like a towel scrunch. Hold, release.

Uses: The posts and textured top give your toes something to press into.

Trains: Foot muscle engagement and toe control.

03

RAISE

Do: Keep the grip and slowly lift and lower your heels. Hold a wall or chair.

Uses: The trainer under your forefoot.

Trains: Foot and calf working together.

THE SCIENCE

The Moves Aren't New. That's The Point.

GroundForm didn't invent foot exercises. Researchers have studied intrinsic-foot strengthening, short-foot and toe-spread exercises, and exercise programs for adults with flexible flat feet. GroundForm puts familiar training concepts into one simple setup.

The research is on the exercises, not on GroundForm itself as a product.

Intrinsic-Foot Strengthening

Studied for training the small muscles inside the foot.

Short-Foot + Toe Spread

Studied for how they activate the muscles under the arch.

Flexible Flat Feet

Exercise programs studied in adults with flexible flat feet.

View The Research

Here's what we're basing this on:

Intrinsic-Foot Training: [1] Scoping review of intrinsic foot-muscle strengthening in adults with flatfoot - Journal of the American Podiatric Medical Association (PMID 41745135).

Short-Foot + Toe Spread: [3] MRI study showing short-foot and toe-spread exercises activate intrinsic plantar muscles (PMID 27690528).

Flexible Flat Feet: [2] Randomized controlled trial: 6-week exercise program, measurable improvement in arch alignment vs. control (PMID 36526555). [4] Network meta-analysis of exercise therapies for adult flexible flatfoot (PMID 39261538).

What You're Training

TOE CONTROL

Move the toes on purpose.

TOE SPREAD

Before You Order

Can't I just do these exercises without GroundForm?

Yes, many foot exercises need no equipment. GroundForm puts the movements into one dedicated setup that's easier to start and repeat.

Do I need to stop using insoles?

No. Support and training do different jobs. Keep your insoles and add a few focused minutes of training.

How do I use it?

SPREAD → GRIP → RAISE. Spread your toes between the posts, grip and press into the trainer, then keep the grip while you lift and lower your heels.

Can I use it seated?

Yes for spread and grip: couch, desk, in front of the TV. Heel raises are done standing, holding a wall or chair.

Will it change my arch?

We don't promise that. GroundForm trains the muscles under your foot and builds toe control. It isn't a treatment, and results vary.

Is it only for flat feet?

No. It's built with low arches in mind, but anyone who wants to train their feet can use it: walkers, runners, people on their feet all day.

What are the metal points?

Small magnets built into the textured surface. We don't make any therapeutic claims about them.

Is GroundForm safe for everyone?

Not recommended for people with pacemakers or implanted medical devices.

What's the Massage Ball for? How big is it?

An optional extra for rolling under your foot before or after your routine. It's 2.8 in across and about 4.4 oz. It isn't one of the three moves.

How long does shipping take?

Typically 7-15 business days. See the shipping estimate at checkout for the most accurate delivery window.

What if it's not for me?

You're covered by our 30-day guarantee. Try it at home. If it's not for you, send it back.
