Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a crossover trial where participants will receive each intervention. The initial appointment and subsequent appointments will be 2 hours in duration.

There is no wash-out period between treatments.

Balance-enhancing indoor shoes:

The balance-enhancing indoor shoes include features to improve balance performance such as: (i) adequate fixation and (ii) textured insoles. Participants will be provided appropriately sized balance-enhancing indoor shoes by a registered podiatrist during an appointment in the Podiatry Clinic Research Room at La Trobe University, Melbourne (Bundoora) campus.

Participants will be asked to wear the provided balance-enhancing indoor shoes as much as possible when indoors for a six-week period.

Adherence will be measured by an orthotimer® sensor. These sensors will be embedded into the sockliner of the balance-enhancing indoor shoes prior to participants receiving them. The orthotimer® sensors are small enough that when placed strategically into the shoes sockliner, they will be imperceptible.

Comparator / control treatment
This is a crossover trial where participants will receive each intervention. The initial appointment and subsequent appointments will be 2 hours in duration.

There is no wash-out period between treatments.

Minimalist indoor shoes:

Participants will be provided appropriately sized minimalist indoor shoes (Basic Print Scuffs™) by a registered podiatrist during an appointment in the Podiatry Clinic Research Room at La Trobe University, Melbourne (Bundoora) campus. The minimalist indoor shoes incorporate features such as high flexibility, low heel to toe drop, low weight and low stack height. This shoe aligns with the consensus definition of Esculier et al., 2015 (https://doi.org/10.1186/s13047-015-0094-5).

Participants will be asked to wear the provided minimalist indoor shoes as much as possible when indoors for a six-week period.

Adherence will be measured by an orthotimer® sensor. These sensors will be embedded into the sockliner of the balance-enhancing indoor shoes prior to participants receiving them. The orthotimer® sensors are small enough that when placed strategically into the shoes sockliner, they will be imperceptible.
