The Duncan F2F is a special comfortable shoe that you can walk in all day long. The shoe has a flexible rubber sole, a leather inner lining and a removable footbed. The special thing about this shoe is that it is an F2F (Fit 2 Feet) model. Fit 2 Feet shoes adapt to your feet, without you being able to see on the outside. They even have a special cutout for people with hallux valgus. This way we ensure that the shoe stretches where you need it, while it retains shape and sturdiness in other areas!
