Chromate can be found in shoes. A person who is sensitive to chromium salts may develop a dermatitis over the exposed skin.
Chromium may be present in a shoe because of:
(1) leather
(2) environmental contamination (often occupational)
Risk factors:
(1) direct skin contact with the chromate-containing material
(2) excessive sweating (hyperhidrosis) or other foot moisture (to solubilize the chromate)
Clinical findings:
(1) The dermatitis is distributed over the foot and/or ankle.
(2) A patch test to chromate salts is positive.
Wearing socks, keeping the feet dry or wearing different shoes is usually sufficient to prevent recurrence.
