7C = 44F. Definitely ok to run barefoot in dry weather (I've done it numerous times this spring already). Might be a bit on the uncomfortable/cold side in wet weather or for those that are used to warmer temps though, so I'd try shorter distances your first couple times out.
I got frostbite from a 15 minute run in 9f, though there was snow on the ground which makes a biiiig difference. Dry ground is much safer than wet.7 degrees Celsius is perfectly OK. 7 degrees Fahrenheit is very cold, and very probably not OK.

It was mild frostbite but the fluid oozed for days.
In snow/ice I now wear track spikes
