Nothing on the net for a review of these specific to windsurfing, just some happy SUP riders but they don't deal with footstraps so I decided to roll the dice on a pair.
I ordered 1/2 size down from my shoe size (as was recommended) which was about right although the big toe pocket was a little small (this is a common complaint for me). I did the heat molding and they definitely changed shape but I think I should have just kept the hot water localized to the toe box since I gained some unneeded room in the heel.
In the area I sailed there is a long walk over pavement, crushed rock, driftwood and finally barnacles. The soles so far show zero wear which is favorable compared to other surf booties I've used.
On the water they are the warmed 3mm I've ever used. 5 hours yesterday in 10 degree water without any complaints. The upper seals keep them from flushing extremely well.
My footstrap sizing feels like it could be reset down close to bare feet and I wasn't stuck at any point (a previous frustration). I think the material for the shoe section will also not cause the strap wear I've seen with other booties.
Time will tell on the durability front but if they last 12 months I'll get another pair next year. I'm hoping to also get some Atans for comparison.
