Avoid riding in sandals and you probably won't get burned.

I have barely a 30' inseam and I wear 8" boots and I don't get burned, though I have gotten warm and quickly moved outboard of the pipes very occasionally. Foot and leg position gets intuitive after riding awhile.
One of my bikes has Hwy pegs on the forward guards with no offsets (just short clamps) and if I'm not careful, my calves rest on the rear valve covers, and that gets warm right away ("crap, I did it again"). I really need to put offsets on it like I have on my other bike. Though I hardly ever use Hwy pegs anymore because of traffic everywhere.
And both bikes have floorboards, not pegs, which I prefer. Which do interfere in putting feet to ground more than pegs. No big deal.
I can't help with the phone question.
