I wear a women's size 8.5 shoe and want to use these inside my new size small Aqua Lung HotShot fins only because my next dive trip will be in cooler waters ... I would like the sock to be warm and comfortable yet still fit inside the fin pocket ... so do I order size small or medium?
JEAN M I wear a size seven shoe and found a small lavacore sock that fit very well, but it didn't seem to keep my feet any warmer. The lavacore socks were hard to get off and didn't dry very fast. I was diving in water around 75 and wasn't cold in a five mil. But I went back to my regular socks I wear under my booties and didn't notice any difference. I don't think lavacore is worth the money. Hope this helps. Jean
MARITES M I wear a women's shoe size of 5, I bought a small Lavacore by Oceanic Socks. It was slightly big on me, but not by much. It kept me very warm. I think small will be too small for you.
TSE LYNN L I wear women's 7.5-8, and ordered a medium. It is not snug, but fits like a comfy sock (slightly loose). Using them with Medium Force Fins with narrow foot pockets so I'm not too worried about excess fabric.
ERIK W The only reference I can offer is that I wear men's fins size 9-10 and men's shoe size 10.5. I got a size medium lavacore sock and it works perfectly. I love this product. Hope this helps.
DOMINI Y I can't help with size question, but this is a good product with sufficient thickness to offer real protection. I had several different socks and I like this most. The stitches are in the right place unlike some other run right in the middle which makes uncomfortable when walk around on the deck of the boat.
KENT K My wife has about the same size foot and uses HotShots. She has size S
KEITH H I would suggest medium
JANET S I wear a womens 9-9.5 shoe.
I'm wearing the lavacore in a medium and it fits great.
You are right on the edge of their sizing chart. but I have noticed in this sock that the heel area is not as defined as scubapros. so I would think you would be OK in a Medium. I have let me friend use them and she does wear an 8.5 women's shoe. They fit OK for her, she does have a real high arch so they did fit her snuggly. as well but we both are wearing them with full boots. I love the lava core product.
JAMES L I returned mine, I didn't like them at all! Save your money on these!
Frank L You may want to consider a neoprene sock or even a boot with those fins. Medium would be the size for you.
