We present four patients who developed allergic contact dermatitis on their feet after wearing Keds Canvas sneakers. All patients underwent patch testing with the North American Contact Dermatitis Group (NACDG) Baseline series (Chemotechnique Diagnostics AB, Vellinge, Sweden), and various other allergen trays, depending on the clinical scenario, including a glues and adhesives series (Chemotechnique Diagnostics AB), a shoe series (Chemotechnique Diagnostics AB), and a textile tray (Chemotechnique Diagnostics AB). All 4 patients developed positive reactions to the thiuram mix, as well as to pieces of their shoes. We initially believed that thiuram accelerators were used in this type of rubber-based canvas shoe. However, subsequent chemical analysis failed to identify thiurams in two different pairs of shoes.
