WalkitoDownload AppThe evidence behind the program
Walkito is not a set of exercises we invented. It follows published rehabilitation protocols, in the order the research supports, at the doses the trials used. This page lists the studies it is built on, what they found, and — just as importantly — where their evidence stops.
Pain and arch shape are two different problems
The program runs two tracks in parallel, because the research treats them separately. Exercises targeting the small muscles inside the foot improve balance, strength and arch posture — but a 2022 systematic review found they do not improve pain on their own.
High-load calf strength training does the opposite: it moves pain quickly, but is not designed to change arch shape. Running one track only would leave half the problem untouched, so Walkito runs both from week three onward.
Strength training moves pain faster than stretching
In a randomised trial of 48 people with plantar fasciitis confirmed by ultrasound, participants did either high-load strength training or plantar-specific stretching. At three months the strength group scored 29 points lower on the Foot Function Index (95% CI 6–52, p = 0.016).
At twelve months the two groups had converged — 22 against 16, no significant difference. What this means: strength training produces faster improvement, not a more complete one. That is why Walkito promises speed, and never a cure.
The protocol Walkito uses follows this trial directly: single-leg heel raises on a step, a towel under the toes, three seconds up, two seconds held, three seconds down, every other day, with load increasing across blocks.

The arch responds to training — given enough time
In a randomised trial of 52 people with flexible flat feet, a six-week program of foot shortening, ankle work, hip strengthening and stretching improved navicular drop by 0.4 cm and arch angle by 16 degrees more than the control group. This trial scored 8/10 on the PEDro quality scale.

A 2024 meta-analysis of short-foot training found that only programs longer than six weeks produced significant improvement in navicular drop. Shorter programs showed no measurable effect. That is why Walkito’s arch work runs for a minimum of six weeks. The app does offer a six-week plan, and the honest reading of this meta-analysis is that it sits at the boundary: long enough to train, not long enough for the arch finding to apply. The twelve-week plan is the one this evidence supports.

What clinical guidelines recommend
The 2023 clinical practice guideline from the Journal of Orthopaedic & Sports Physical Therapy grades the evidence for each intervention.
| Intervention | Grade | In Walkito |
|---|---|---|
| Plantar fascia and calf stretching | A | Daily, from day one |
| Taping, 1–6 weeks | A | Recommended in week one if pain is high |
| Night splints, 1–3 months, for first-step pain | A | Recommended when morning pain is reported |
| Resistance and strength training | B | The core of weeks 2–12 |
| Orthotics used alone | B — do not use in isolation | Not recommended as a standalone fix |
| Therapeutic ultrasound | A — do not use | Not included |

The guideline also advises against complete rest, which increases stiffness. Walkito modifies load instead of stopping it — on a high-pain day the session gets shorter and lighter, but it still happens.
Heel pain often returns — so the program doesn’t end
Recurrence is common enough that stopping at week twelve is the wrong shape for this problem. After the program, a maintenance phase keeps two sessions a week and retests every 28 days, to catch regression before it becomes pain again.
What we measure, and what we don’t
Walkito tracks progress with physical tests every two weeks: single-leg calf raises to failure, single-leg balance with eyes closed, and arch hold time. These are measured, not estimated, and cannot be inflated by using the app more.
Walkito can also read walking asymmetry from Apple Health, which iPhone estimates automatically. We compare it only against your own baseline, never against a population norm — because none exists. A secondary analysis of a trial with more than 800 runners found that gait asymmetry did not predict injury. We will tell you when your walking pattern changes. We will never tell you it means you are injured.
What Walkito is not
Walkito provides exercise programming. It does not diagnose or treat any condition.
The evidence above applies to flexible flat feet — where the arch reappears when the foot is lifted off the ground. Rigid flat feet are a structural issue that exercise will not change.
See a clinician first if your pain followed an injury or fall, comes with numbness, tingling, burning, swelling or warmth, wakes you at night, or if one arch has flattened suddenly as an adult.
