It’s been my experience that Xcel Drylock Split Toe Booties are some of the best on the market. Xcel also makes them in 3mm, 5mm, and 7mm. Shop according to your session duration to water temperature ratio.
I like 3mm booties in Southern California, 5mm for Central California, and 7mm for very cold water and SCUBA diving.
If you want to save a little dough, Xcel also makes a great boot called the Infinity. I’ve used both the DryLock and Infinity series, and although I noticed the DryLock’s were a bit better all around, the difference is not substantial.
Check them all out at XcelWetsuits.com. You can also get a discount buying them through our Amazon links, but I recommend you try them on for size at your local surf shop first.
