What would you choose between pitches if you had the choice: Comfortable sandals or safe footwear No more need to make a choice between the two you can have both! The 3F Vario System transforms a lightweight approach shoe in a flash into a comfortable, relaxed sandal. The sandal protects your feet with a soft, buttery upper and also gives your forefoot plenty of room. THis is an ideal symbiosis with a quick, practical closure system and a special approach design together with the superbly ventilated cushioned upper of Air Mesh.
