No worries TP, with skipping you tend to be on the balls of your feet (rather than heel striking, as you would when running) - so skipping places different stresses on toes, ankles and calf / shins and sadly even most gyms are solid floors unless they have a fitness studio.
Just want to see ya out there kicking butt - asap
