When treading water in full gear, the frog kick will help me out if I can use my arms too. Is there a time when you have to tread with only your feet and holding your arms above your head, out of the water?
Negative. You can use your hands the entire time, although they are mostly for stability and balance. Your legs provide most of the treading action. Big, strong kicks should do it, especially with those boot soles helping you out.
