<sigh> Yes, I have Jet fins. No, the air is not in the feet, as I wear neoprene booties.
In my fusion, in a single, the gas slowly migrates to my lower leg when I am in trim. I slowly tip forward. Unless I continuously take an upright position to re-migrate the gas, I will turn upside down.
Or, I keep my trim about 30o and the gas does not migrate. Sacrilege! :shocked2:
Too much air in the suit?
