Crocs (NASDAQ:CROX), the favorite footwear du jour of stockholders thanks to its skyrocketing value, may have stumbled a bit last week when the Japanese government's National Institute of Technology and Evaluation issued a warning to wearers.

Apparently, in just the past few weeks 40 Japanese wearers of Crocs or imitations, mostly children, have had their footwear caught in escalators. One five-year-old lost three toenails and broke a toe, and six other children were injured.

For those who might discount this as alarmism, I might point to Mattel's (NYSE: MAT) recent experience with lead paint. The slightest hint of peril to one of our nation's children can inspire a tsunami of reaction from concerned parents, not something a trend-dependent product like Crocs needs.
