The Short Foot Exercise

The short foot exercise is a neuromuscular strengthening technique primarily targeting the intrinsic muscles of the foot—specifically those responsible for supporting the medial longitudinal arch (like the abductor hallucis). The goal is to “shorten” the foot by contracting the arch without curling the toes or lifting the heel. This activation essentially draws the ball of the foot toward the heel, improving the dynamic stability and control of the arch. It’s subtle but powerful. Over time, this can enhance foot posture, balance, and even improve kinetic chain mechanics up through the ankle, knee, and hip.

How to do it? Sit or stand with your foot flat on the ground. Without curling your toes, gently press the tips of your toes into the floor and try to pull the base of your big toe toward your heel. You should feel a slight elevation in your arch. Hold that position for 5–10 seconds, then relax. Repeat for 8–12 reps per foot, progressing from seated to standing, and eventually to single-leg stance for added challenge. It’s important not to let the toes grip or over-flex—this would recruit the wrong muscles and defeat the purpose of isolating the intrinsics.

This exercise is especially valuable for people with flat feet, plantar fasciitis, or postural instability. It’s also increasingly used by athletes looking to fine-tune proprioception and balance. Over time, consistent short foot work can contribute to stronger arches, reduced foot fatigue, and better overall alignment. That said, it’s not a magic fix on its own. For best results, combine it with broader foot and ankle mobility drills, proper footwear choices, and gradual strength training to reinforce the whole lower limb system.

Supination Resistance

Supination Resistance is a concept of determining the force needed to supinate the foot. This is considered important in foot orthotic prescribing as it is helpful to determine how much force if needed from the foot orthotic if the foot is overpronating.

Supination resistance refers to the amount of force required to supinate (invert) the foot around the subtalar joint during gait or clinical testing. It’s a key concept in biomechanics and podiatry, because it helps clinicians understand how easily or how much effort it takes for a person’s foot to resupinate during walking or running. Normally, after the foot pronates during stance phase (to absorb shock and adapt to the ground), it needs to resupinate for effective propulsion. If the foot has high supination resistance, it means a lot of force is required to achieve this motion, potentially leading to inefficient gait mechanics and increased risk for overuse injuries.

Several factors influence supination resistance, including the alignment of the subtalar joint, midtarsal joint mobility, body weight, and even soft tissue flexibility. For instance, individuals with a medially deviated subtalar joint axis often have higher supination resistance because ground reaction forces act more medially, increasing the lever arm for pronatory forces. Conversely, someone with a more laterally placed subtalar axis may have lower resistance. Clinically, high supination resistance is often associated with persistent pronation, flat feet (pes planus), and conditions like posterior tibial tendon dysfunction, while low supination resistance may correlate with rigid high-arched feet (pes cavus) that don’t adapt well to ground surfaces.

Understanding supination resistance is important for treatment planning, especially when prescribing foot orthotics. Patients with high supination resistance may need orthotics that provide more aggressive arch support or medial posting to control pronation. On the other hand, for those with low resistance, excessive correction can actually destabilize the foot. Some clinicians use devices like a supination resistance meter, but often manual testing provides sufficient clinical information. Ultimately, evaluating supination resistance helps personalize interventions, optimize gait, and reduce injury risk.
