Umbro is going to review its policies after finding out that its Zyklon trainers/sneakers share their name with a crystal used to exterminate millions of Jews in concentration camps during Hitler's Nazi regime.
Umbro, makers of the England football team kit, said the name was not designed to have anything to do with the crystals and the mistake was purely coincidental. The name was chosen in 1999 by a designer and only appears on the boxes and not the shoe.
The co-founder of a holocaust center said: "I... find it hard to believe Umbro's assertion that the naming of the shoe was 'purely coincidental'." An Umbro spokesman said: "I think in future we will be checking the names we use more carefully."
