Jack,
there are people responsive to look, marketing & advertising. To me
paying twice as a much for Omer Ices than for any other thermoplastic fin like the Cressi Garas mentioned above is a bad investment.
The 'cool' looks of the Ices does not translate into any better freediving performance compared to other thermoplastic fins, and you may also want to consider the following: A manufacturers warranty against blade failure (you would not be the first

) will not help you any when trying to resurface
with one fin from depth.
Contrary to Omer the Cressi Garas have an unblemished track record for many years.
If you have the cash for Ices go for a better fin (fiberglass or even carbon).
Cheers,
ulysses
