Springline's bespoke lasts are genuine bespoke one-offs not some adjusted commercial lasts. Yes, but springline bespoke last not measured for arch support (they tell me this) when use 3D machine. Shoe maker will have to make further alteration to last by cutting part off (bottom area) to make room for inner supports for proper bespoke. lt can be problem if shoe maker is not last maker and know feet good. Machine can never predict how foot behave, still need human hand to perfect last. That me understanding, tell me if me wrong.
