The 32.5″ Johanne Defay Pro model is one of the newest of the SmoothStar Surf Trainers. It has been closely developed with Female pro Surfer Johanne Defay and mimics her powerful carving surf turns. The 32.5″ model has the deepest concave of all of the smaller high performance models under 33″. The deeper concave enables riders to hold the rail more than other models and helps maintain compression through the turn, just like surfing.
