I am so, so happy to hear the news!

Finally something! Go Matthew! Being able to tolerate a bare foot IS a big deal. It is wonderful you got the pool set up in your yard. That will make recovery more of a social thing too. That wonderful Michigan summer is around the corner.
Is the color improving at all? Does he still have much atrophy or has the muscle mass on his affected leg returned? I still discolor but it has improved over time and seemingly as I have gained muscle mass. Just measured my calf this week and it is finally back to the same size as the other one! Took 10 months of work and I don't think really pumped up till I could walk more consistently. I wouldn't worry too much if muscle mass is taking time to normalize, so long as there is slow steady imrpovement. Does Matthew's leg look normal when he is using it? That sounds like a good sign if so. Darn circulatory symptoms! Those drive me nuts.
Sending hugs, Littlepaw
