Oh my @kissmyaxe94! Why did I missed this out! 😭 You look effortless on the video! It's not about how deeper you can go, it's all about being relax and just enjoying the view underwater.

And congrats on the new fins! Nothing wrong with buying the fiberglass right away. Bought one for myself than the plastic ones and its really worth it. Your friend was right too about "upgrading in the future".

Your foot pockets are way too big for you! My shoe size is 38-39, but my foot pockets are only size 35-36 and I use a 2mm socks not to get blisters and for my feet to fit well. If you can, you can trade or sell your foot pockets in freediving groups in FB for a smaller size or you can just simply purchase another foot pockets plus neoprene socks. When you purchased your fins, did they gave you those other extra screws and those "little black thing"?
