Effect of recommended footwear fit upon in‐shoe pressures in feet with diabetes—An exploratory study

Diabet MedPublished Exploratory study

Authors' conclusion

This exploratory study suggests that larger toe gaps may be associated with increased hallux plantar pressures, in some cases exceeding 200 kPa-a commonly cited threshold associated with increased DFU risk.

Study context

Population
People with diabetes walking at 1 m/s ± 5% in standardised footwear17 with data available
Participants
25 people
Comparison
Toe gap 1.5-2.0 cm vs 1.0-1.5 cm vs 0.5-1.0 cm in standardised footwear
Primary endpoint
Mean in-shoe peak plantar pressures
Methodological detailsstandardised footwear, within-participant comparison of three toe gap ranges
  • Standardised footwear
  • Within-participant comparison of three toe gap ranges

Primary result

As reported in the abstract

Mean right hallux in-shoe peak plantar pressure

P = 0.03

Further findings

Habitual footwear fit

More three-quarters of participants wore habitual footwear of incorrect length
Almost half wore incorrect width
