Advice re: Problem with bottom of right big toe & fins

A few weeks a go I got my Advanced Open Water Certification.

Everything went well except for the fact that I got some ulceration
from the fins I was using on the underside of my right big toe even
though the fin felt comfortable on my foot.

It was really raw and affected my walking but it has improved in the
last week or so. I'm leaving for Roatan on Saturday and want to avoid
more problems so I'm bringing adhesive tape and gauze.

Does anyone have any suggestions to protect my right toe while diving.

Any comments and suggestions will be appreciated.

If its not fully healed and you dive anyway, It will probably get some
kind of microbes in it so bring some antibiotics. Its amazing how quick
infection can grow in a small wound exposed to sea life.

Dr Yak...

Try wearing socks. You can even get some silk dive socks, but I would
bet that some cheap white ones will work fine for you.

My dive booties used to chew me up in a few places. Then a looooooonnnnnngg
time professional underwater photographer told me to get some lycra socks.
Followed his advice and I've had nary a problem since.
