Toe-In Angle Guide
Once you have chosen the correct front fin size, you also need to know the front box angle (toe-in) of your board. This is extremely important — otherwise the fin will not work properly and it will only create unnecessary drag. You will go from Hero to Zero....
The SURF PRO front fins feature a radical asymmetrical profile. The Toe-In range could go from 1,75° up to 3°. Anything out of this range it will create an unwanted drag. We will create a small formula for you to get the best fin size compared to your board/weight.
Our fin models are available with 0°, 1°, and 2° toe-in options.
