Hey, I decided the only was I was going to get around to making my first post was to ask a question so I have a question. I'm not certified yet but I've signed up for a open water certification class and have bought my mask fins snorkel and booties. I think my fins may be a little too small. I've tried them out in the pool and after a little bit the top of my feet start to ache, and I got a cramp in my calf when I tried to go a bit faster. The PADI manual says the pocket should come to the point where my ankle meets my foot, but it's really hard to see where they consider that to be by the picture in the book. I think it's about a inch off but I might be wrong so I've included pictures (they're Aqua Lung Blades 2 btw). I don't care too much about going fast I just don't want the tops of my feet to ache.
