Summary
Brief summary
The aim of this project is to evaluate the effectiveness of reducing painful callus (hard skin) on the bottom of the feet (using scalpel debridement) versus no reduction (using a sham debridement technique).
This study is double-blind: both the participants and the assessors will be blinded.
