I picked these because my other boots kept leaking water in the seams and ankle and freezing my feet, these are sealed and welded so no more leaks. The interior is what gets me, nice plush warmth. I had no idea the heat loss in my feet was contributing to my total body heat loss. The impact was much greater than I thought. These boots feel like a second skin, I thought they might be bulky but not at all. I wore the kayaking and stand up paddleboarding in the surf and they performed very well. Just gave your business name to a bunch of friends who will be shopping with you all - you are a great helpful bunch.

I am in 74 degree water and having a 7mm both saves me from blue toes!

I am a size 10, and found the 10 size was too snug. Exchanged for an 11, which weren't at all too big, and were still snug enough to provide very good control. I used them the other day in 29º weather (water still liquid:) . Feet stayed warm enough to stay out for 1-1/2 to 2 hours. Big toes got a little chilled, but tolerable. Might help to do a fleece or thin wool sock as well, like I have done in the past with other booties, but I didn't try it yet.
