Mare's or beuchat

The one that fits the best. A comfortable footpocket is very important. Get a good footpocket, then upgrade the blades later to fiberglass or carbon if desired. The Mares will fit wide feet.

I have the Mares Razor fins, they fit me well and have been working well for me here in Northern California.

Both are good, Beuchat has a narrow footpocket in comparison.

Used beuchat comps and fiberglass for years and now switched to Mares razors. Definitely wider footpockets, which I prefer cause now I can use them with both socks on or off and either way they fit perfectly (I have narrow feet). And for quality, I have the idea one of them (possibly mares) keeps a very close eye on the other's products. Just look at all their suits fins snorkels. They look very similar, coincidence? I don't think so.. As for the fin, the comps where a bit to stiff for me. Got cramps being in the water for over 6 hours so switched to fiberglass which was great but seemed fragile. Now back in Europe decided the Razors (grey blades, similar to mundial sport) probably serve me best. Haven't properly used them but they seem like a good fin. Sooo, whatever one's cheapest mate and of course fits well.

Good luck!!

if you are not using socks then i will go for Beuchat Mundial fibra. the footpockets have much elasticity and more comfortable specially if you have weak ankles.

If any shops have a free testing out there so there wouldn't be any prob. to choose the best fins that suit your recommendation.

cheers.
