Very efficient, it is not easy for me to find the correct size of foot pockets, I am always between 2 sizes. The C4-400 is fine, the carbon is just awesome and the fins are light. Classy expensive fins. Top world class efficiency. As a freediver instructor, I test sometimes the fins's students. Alchemy is another world clearly.
Good fins.
These fins are a game changer! I owned a lovely pair of V3 before, but these are entirely different. I have the new blade fitted with the C4-400 foot pockets. They are amazingly light and responsive, but the angle makes a huge difference. They feel very easy on your legs and make longer swims way more efficient in terms of lactic build up. Perfect competition fins, for a great balance of power to work - I am really happy with them!
I love Alchemy very much. Alchemy presents me a new world.
I am satisfied with the lightness.
Very nice!
I love these fins! They've completely changed my diving experience and I find myself pushing further knowing I have the right gear.
Very good!
Amazing product, it feels like I don't have any fins on but the propulsion of them is out of this world. Tried them with c4 300 and 400 foot pocket, in my opinion the v330 and the 300 foot pocketis the perfect pairing.
I loved how its a shorties but the power of the fin is amazing. And it's very handy when it comes to traveling because its a shorties. I also love how light it is and it doesn't make my ankles hurt.
