Mimo, I actually just compared a pair on the F last that I own and I would say the P2 last is a 1-2 mm shorter than the F last in length, but wider in the forefoot and the toe box. P2 is a more classic rounded last. I hope that helps. PM if you think it will work for you. They are an awesome pair of shoes and I already put a re-order in with Reszo, as I imagine they will find a happy new home soon.
