Nah you can't really bend them in, and if you try too hard you'll break part of the assembly.
Are the already mounted? If not it's pretty simple to swap the brakes, there's a thread at the top of this forum with a video guide.
Derp, well done me, of course they're already mounted.
Only way to change the brake is to un-mount the binding, unfortunately.
I'm surprised your shop mounted them like that, it's always gonna be a problem. Don't ski them like that, the first time you land switch on a slight angle you'll totally butcher the brakes.
Then the legs will be 5000 miles long and probably bend really easily.
You have 2 real options.
A. First, unscrew the heelpieces (if you do it carefully, and put the screws back in carefully with fresh glue you won't do any damage). Then get brakes from old swap meet skis, someone on NS or even direct from Rossi and install them as per the video on here. It's really quite easy. Getting the spring back in is a bit gnar but if you're patient with it it's no problem. Re-mount heel, done.
B. Pull the 'feet' off the brakes, cut them shorter, bend them as straight as you can then bend them 90 degrees again. Put feet back on. I don't know how hard this would be with the bindings on the ski. Probably REALLY hard.
You're really better off doing option A, do it once do it right. It won't do anything bad to your skis.
