i update the situation because the experience has been new for me and quite a surprise.
the long plaster cast revealed to be extremely confortable for my ankle, as absurd as it may sounds my leg is perfect in this huge "prison". but it also difficoult to move around. the only problem ias the persistent swelling, even after 6 weeks the cast still feels tight.
on nov 20th i started to put weight on the leg and 0 pains, i use crutches only for balance. but, as you can imagine, it's difficoult to "walk" on that big cast so i can't wait to have it removed.
so you can imagine my delusion when i recived a call from the clinic to postpone the visit 10 days!
anyway... should i bring a large shoe or a more supportive one? injury happened with flat canvas shoes so i don't like too much the idea of wearing a similar one as my "1st shoe", but i also think that the swelling could be a problem with running shoes.
