I was never able to find any springs that fit my Mares fins. That's why I went with the bungee.
FYI, on my Mares fins I've used TUSA TA-80 Spring Straps purchased in 2009 and they've been awesome for the last 9 years. Before that, I used Manta Spring Straps purchased in 2003 and 2004. They still work great, but the TUSA's are nicer. (Mares Fins with these springs: Raptor, Volo Power, and Plana Avanti Quattro)
