Rocker-bottom soles may alter balance and raise fall risk for people with diabetes

A notice on the Podiatry Arena forum flagged a study in Gait & Posture (Albright BC, Woodhull-Smith WM, 2009) that examined how rocker-bottom soles affect postural control. The study reported that rocker soles alter the postural response when the body experiences a backward translation while standing. The forum headline and summary connect that finding to diabetes, suggesting rocker-sole footwear may increase fall risk in people with diabetes.

The specific experimental finding reported is that rocker-bottom soles change the way people respond to a backward translation during stance. Backward translation refers to a platform or surface moving backward under the feet, which requires the body to generate corrective postural responses to avoid losing balance. The study authors concluded that the rocker sole altered that corrective response.

Why this matters for people with diabetes

• Evaluate balance before prescribing rocker-sole shoes. For diabetic patients, especially those with neuropathy or prior falls, perform a targeted balance and gait assessment before recommending rocker soles.
• Consider alternatives. If the clinical aim is off-loading or pressure redistribution, compare rocker soles with other off-loading devices and orthoses whose effects on postural responses are better understood for that patient.
• Monitor after fitting. If a rocker-sole shoe is provided, recheck balance, gait stability, and patient confidence during supervised gait trials and early follow-up visits.

• Report dizziness or instability. Patients who feel unsteady after switching to rocker-sole footwear should stop wearing them until reassessed.
• Start slowly. Trial walking under supervision or in a low-risk setting (flat, uncluttered floor, with a clinician or support) can reveal problems before the patient uses the shoes in daily life.

The item appeared on Podiatry Arena, a professional forum with research summaries and discussions. The forum posted the Gait & Posture citation and framed the finding as a potential fall risk in diabetes. Related forum threads include other footwear and biomechanics topics such as rocker-shoe running biomechanics, plantar pressures in diabetic patients, and the effectiveness of different off-loading devices.

This summary reports the study's experimental observation (altered postural response to backward translation) and the forum's interpretation (may increase fall risk in diabetes). It does not quantify the magnitude of risk, nor does it present additional empirical results beyond the cited finding.

Rocker-bottom soles can change how the body corrects for backward perturbations during stance. For people with diabetes—who may already have balance vulnerabilities—those changes could increase fall risk. Assess balance and gait before prescribing rocker-sole footwear and monitor patients closely after fitting.
