sorry

i didn't mean it that way..
Anyway, I understand how you feel.. I live in a tropical country too..
Those SPD sandals do come in handy.. I'm posting a pic..
Good thing is, you can walk in them, even in the sand, i guess.
those baggy shorts may help, if you are using those loose trunks.. I simply assumed you used the tight ones, like cycling shorts..
If you get irritations on the way back, perhaps its the saltwater..
