Parks advocates are calling for bilingual signs warning kids and parents to keep their shoes on.New York City Park Advocate Geoffrey Croft says the signs are necessary following recent incidents in which children running barefoot were burned from black rubber on playground floors. The ground temperature of some parks were recently measured at close to 135 degrees Fahrenheit.

Advocates say signs in both English and Spanish are necessary. They also want the signs to explain why shoes need to be kept on, because a sign that reads ?no bare feet? may not be enough.

Croft said to really solve the problem, more heat protection is needed. ?The solution right now is to put trees [over the parks]. A canopy,? said Croft. ?They?re doing this all over the country.?

The Parks Department says it will ensure signs are posted at every playground and in different languages where appropriate.

Playgrounds not always a good place to cool off
