Equipment improve

hey, christmas is coming and i am looking foward to bring my board (equipment ) in better shape.
i am surfing now for 6 years (month a year /from austria=no surfing) and i allways used cheap black plastic fins - my main concern for my new fins is more speed ! do you have any recommendations ? maybe around 60-100 dollars ...
also i am lloking for new (the thing on the tail where your foot stands on) - any suggestions ?
direct amazon links would be great
i have 6.6short board ( i am allmost 2 meters so i need a little bigger one)
thanks for all tipps ! cheers
