booties

[Subber]

I only wear booties when it is pretty cold.

I wore my O'neill surf booties but noticed my feet
got cold from the evaporative cooling effect.  In fact,
I felt my feet would have been warmer without the booties.

Then, I found some O'Neill Gooru Tech ST 3MM Booties
(luckily on sale at their outlet).
They have a "Liquid rubber sealed exterior" so their
is no evaporative cooling like most other boots.

They are very flimsy - feel like slippers, which I like.
- not sure how much protection if you stepped on something sharp,
but better than barefeet.

The only drawback is they are very difficult to get on and off.

XCEL booties are great. Very comfortable.

+1 on XCEL booties. Got a pair at the start of the year and really like them.

I am a cold water Sup surfer. Need warm booties 9 months of the year, tight fitting and can be difficult to get on and off. I have found that if I put bee's wax (Chaphans salad bowel wax........yes I am a wood worker) on my heels prior to putting the boots on it makes it simple to get on and off. I have not noticed any deliterious effects on the rubber and great to soften foot callus.
