Minneapolis--The XXII Winter Olympics in Sochi, Russia, ended nearly one month ago, but the games' ability to set global trends is running (er, skating) at full speed. One of the bigger fashion trends to emerge from the seaside resort town, in the shadow of the Caucus Mountains, was the bobsled shoe as casual footwear. Yes, the same shoes designed to provide built, sprinting athletes pushing bulky sleds with traction on ice are being worn by the "average Joe" to carryout everyday activities. One major problem has resulted, however, from school-aged children sporting the spiked gear.: floor damage. "We're not talking a few scrapes here," said Edward Johanson, principal at Bloomington Middle School in Bloomington, Minnesota. "I absolutely love that our children were inspired by the fantastic Winter Olympic Games. I love their passion. But the spikes are wreaking havoc on floors, and nearly all of the flooring in the school now needs replacing. Let's not even talk about the basketball court." This is not an isolated incident, as schools--malls, restaurants, and offices--across the country and around the world have started banning the metal-spiked bobsled shoes.
