beat me to it. It is alot safer than putting them on the handlebars.
Sorry, yes it is perfectly safe.

 

Kind of hard for me to get my feet up by the handle bars, could be uncomfortable. Really what i mean is will they leave marks on the bars if I dont like them?

 

Probably will. I've never taken mine off to see.

 

It's the leg cramps I hate. And, if my wife scratches me behind the ears it makes my right leg kick; putting us into the shoulder.

 

yes, they will leave marks. You want to have the bike upright and figure out right where you want them before you mount them. the 360 brackets give you some adjusting room without having to move the mounting clamps.

 

They work better on the front forks

 

Oh...You mean the CRASH bars? Yep...Put them there..
