Most children are born with flat feet. That soft, rounded sole you see on your toddler is completely normal. A fat pad fills the arch area in young kids, and the bones and ligaments are still flexible enough that the foot flattens under body weight. By age 6 or 7, arches usually develop on their own.

But some children need extra support. Their arches stay low, their ankles roll inward, or they start complaining about tired legs after a short walk. As a posture and foot specialist who has worked with hundreds of families, I see this pattern often. The good news: a few minutes of targeted play each day can make a real difference.

This post covers five flat feet exercises for kids that strengthen arches, build ankle stability, and feel like a game rather than a chore.

What Flat Feet Look Like in Children and Why They Happen

Flat feet (also called pes planus) means the entire sole of the foot touches the ground when a child stands. There is little or no visible arch on the inner side of the foot.

In most young children, this is a normal stage of development. According to the American Academy of Pediatrics' guidelines on flat feet, babies are born with flat feet, and arches typically form between ages 2 and 6. Research published in the journal Pediatrics found that 54% of 3-year-olds had flat feet, but only 24% of 6-year-olds did. The arch keeps maturing well into adolescence.

Two types matter for parents to understand. Flexible flat feet are the most common kind. The foot looks flat when standing but shows an arch when the child sits or stands on tiptoe. This type rarely causes pain and often resolves with growth and activity.

Rigid flat feet are much rarer. The foot stays flat in all positions, and the child may have trouble moving the ankle. This type needs a medical evaluation.

Three factors influence whether flat feet persist: age, body weight, and activity level. Children who spend more time barefoot on varied surfaces tend to develop stronger arches. Kids who are above average weight for their age show a higher prevalence of flat feet, according to research from the International Journal of Environmental Research and Public Health.

When Flat Feet in Kids Need Attention

Flat feet alone are not a problem. The question is whether they cause symptoms.

Watch for these signs in your child:

• Complaining of foot, ankle, or leg pain after walking or playing

• Tiring quickly during physical activities that peers handle easily

• Tripping or stumbling more often than other children their age

• Uneven shoe wear, especially heavy wear on the inner edge

• Ankle rolling inward noticeably when standing or walking (this is sometimes called pronation or valgus positioning)

If your child shows one or more of these signs consistently, it is worth talking to a pediatrician or a specialist. I recommend not waiting for pain to become a daily event. Early, gentle intervention through targeted flat feet exercises for kids can strengthen the muscles that support the arch before problems compound.

One important note: a child who has flat feet but runs, jumps, and plays without any discomfort typically does not need treatment. According to the American Academy of Orthopaedic Surgeons, flexible flat feet in children usually require no intervention if they are painless.

5 Flat Feet Exercises for Kids That Build Stronger Arches

These exercises target the small intrinsic muscles of the foot, the calf muscles, and the ankle stabilizers. I use playful names in my Posture and Feet course so children stay engaged. Each exercise takes about one minute. Aim for the full set once a day, five days a week.

1. Towel Scrunch

This exercise teaches kids to grip the ground with their toes, activating the muscles that lift the arch.

How to do it: Place a small towel flat on a smooth floor. Have your child stand at one end with bare feet. They scrunch their toes to grab the towel and pull it toward them, inch by inch. Each shuffle is one rep.

This is one of my favorite starting exercises because it requires zero equipment beyond a hand towel. Children as young as 3 can do it, and most kids find the scrunching motion funny. If your child struggles at first, try having them practice while seated before progressing to standing.

Reps: 10 scrunches per foot. Ages: 3 and up. Learn more about the Towel Scrunch.

2. Heel Raise with Mini Squat

Heel raises are one of the most effective arch strengtheners. This version adds a fun squat at the top to keep kids interested.

How to do it: Stand with feet hip-width apart. Rise up onto the balls of the feet (the tiptoe trolley). Hold for three seconds. Then bend the knees slightly into a mini squat while staying on tiptoe. Lower the heels back down. That is one rep.

This exercise works the tibialis posterior, the muscle most responsible for supporting the medial arch. You can make it more fun by counting the hold out loud together or by having your child pretend they are a trolley picking up passengers at each squat.

Reps: 8 to 10 reps, 2 sets. Ages: 4 and up.

3. Single-Leg Balance Hold

This balance exercise strengthens the ankle stabilizers that help control pronation.

How to do it: Stand on one foot with arms spread wide like airplane wings. Hold for 10 to 15 seconds. Switch feet. For younger kids, let them hold a wall or chair with one hand at first. The standing foot works hard to keep the arch lifted. Learn more about Single-Leg Balance Hold.

Balance on one foot is harder than it sounds for young kids. Expect wobbling. That wobbling is the workout. Every micro-correction the foot makes while balancing strengthens the muscles that hold the arch in place.

Reps: 3 holds per foot. Ages: 4 and up.

4. Toe Pickup Challenge

Picking up objects with the toes fires up every small muscle in the foot. Kids love the challenge of building a pile.

How to do it: Scatter 10 to 15 marbles (or small blocks, pom-poms, or crayons) on the floor. Place a bowl nearby. Your child picks up one object at a time using only their toes and drops it in the bowl. Race against a sibling or a timer for extra motivation.

This exercise works the toe flexors and the intrinsic foot muscles that standard walking does not activate strongly. If marbles roll too much, use pom-poms or small erasers instead. The goal is precision, not speed.

Reps: Pick up all objects with each foot. Ages: 3 and up.

5. Heel-to-Toe Walk

Walking in a straight line with focus on foot placement builds both arch strength and proprioception (the body's sense of where it is in space).

How to do it: Lay a jump rope or strip of tape on the floor in a straight line. Your child walks heel to toe along the line, looking down at their feet. Each step should feel deliberate. For an extra challenge, try it with a beanbag balanced on the head.

Proprioception is often overlooked in flat feet discussions, but it plays a key role. Children with flat feet sometimes have weaker awareness of how their feet contact the ground. This exercise trains that awareness while building arch strength at the same time.

Reps: Walk the line 3 times (about 8 to 10 feet each time). Ages: 3 and up.

How to Make Flat Feet Exercises a Daily Habit

The biggest challenge with children's exercises is consistency. Five minutes once is easy. Five minutes every day for three months is where results come from.

Pick a trigger that already exists in your child's day and attach the exercises to it. After breakfast works well because shoes are not on yet and energy is high. Right before bath time is another natural window since bare feet are already part of the routine. Avoid bedtime, when kids are tired and less cooperative.

Make it visual. A simple chart on the fridge with five check boxes per week keeps older kids motivated. Younger children do better with a parent doing the exercises alongside them. I do these moves with both my kids (ages 5 and 9) and find that participation matters more than instruction.

Keep a pair of grippy socks or just designate bare feet near the exercise spot. Removing shoes signals to the child that it is exercise time. Routine cues like this help younger children transition into the activity without resistance. If your child attends a sport or dance class, ask the instructor whether they incorporate any barefoot balance work. Many do, and that counts toward arch-strengthening time.

Start with just two flat feet exercises for kids if five feels like too much. Add one more each week. Consistency with two exercises beats occasional attempts at all five. Over 8 to 12 weeks of daily practice, most children show visible improvement in arch height and ankle alignment.

Shoes, Surfaces, and Other Ways to Support Arch Development

Exercise is only one piece of the picture. What goes on your child's feet the rest of the day matters too.

Barefoot time is one of the simplest ways to encourage arch development. Walking on grass, sand, or textured mats gives the foot muscles a constant workout that flat indoor floors do not provide. Aim for at least 30 minutes of barefoot play daily on varied surfaces.

When shoes are necessary, choose options with a flexible sole, a wide toe box, and minimal arch support for healthy feet. Stiff, heavily cushioned shoes do the foot's work for it, which can slow muscle development. My Ultimate Footwear Guide breaks down exactly what to look for by age group.

Avoid relying on orthotics or insoles without professional guidance. The AAP notes that shoe inserts will not help a child develop an arch and may cause more problems than they solve. If a specialist does recommend orthotics, they should be custom-fitted, not off-the-shelf.

One more factor parents often overlook: body weight. Children carrying extra weight put more force through their feet with every step. A combination of regular movement (including these flat feet exercises for kids) and balanced nutrition supports healthy foot development from multiple angles.

Flat feet often show up alongside other lower-body alignment patterns. If your child also has knees that angle inward, check out my guide on knock knees exercises for kids. Many of the same muscles are involved, and combining both routines takes just a few extra minutes.
