The goal of this project is to record the consistencies and gaps in opinions rendered by trained footwear examiners when using the range of opinions published by SWGTREAD. Ian’s results will be based on an examiner completing footwear comparison cases. The conclusions of this study will be published in an article featured in the Association Québécoise de Criminalistique (AQC) journal.

Anyone wishing to participate in this study must have received prior training in the comparison of footwear impression evidence. Both novice and experienced examiners are welcomed.
