Dont buy em´ Dali; you´ll be struck by som kind of annoying and long lasting infection too!!! rofl
Jokes aside, it is indeed a really sweet pair of fins. I bought a pair of 25´s and use them for shallow water fishing (-10m) with a lot of surface swimming. No leg or ankle fatigue at all (as opposed to my Cressi Gara 3000LD). And on my wifes feet, they even helped her going 2 stiff kilometers in head side current in the Red Sea without any whining :girlie
So a very smooth and efficient fin, also due to the gigantic waterrails, which also make the fin steer very straight, and therefore makes it very forgiving for divers with lousy technique and week angles (like me for instance ;-).
There is quite a large angel between blade and footpocket, which makes the fin more relaxing to swim with, and give some extra force to the upkick; really sweet indeed, and the force distribution feels very even through out the entire kick cycle. I did have the pleasure of trying Linda Paganellis Spierre carbon blades. They have similar characteristics and could be a very nice alternative if you are really hard on your fins but insist on carbon blades, since the high rails on the Mustang will eventually wear out and is a 30€ (for 4 rails) spare part. Also I imagine that the flap will eventually be worn down to a point where the material will be so thin that it brakes. That is especially a problem if taking them to the pool alot since you slide the tip over the pool bottom/wall the same way all the time.
And speaking about using the Mustangs for DYN... They are perfect when going forward, buy at the turn, I´ve never tried a finn (including mono) that suck to the wall like this. So the usual turn technique is no good with these fins (but luckily there are more than one ;-).
As for the footpocket, it is as comfi as it looks! It is made for long and narrow feet but the lacing system makes it extremely flexible, so don´t worry. I bought a pair of 39-40 pockets for bare feet and a pair of 43-44 to use with 5mm socks. The second pair was a waste, because the lacing system makes the 39-40 fit better both with bare feet and with 5mm socks. So I have a pair of brand new 43-44 pockets for sale...
Hope this was useful.
Very best regards
