Hey MT, CONGRATULATIONS on your phenomenal progress!!!
Let's keep it up by making it more comfortable for you to run.
I'll give a +1 to the New Balance 1012 shoes. They will give you the *Motion Control* you need and the wide and high toe box you want to avoid those blisters.
Now, about those socks.............. Do NOT wear cotton socks!!!
In fact, do NOT wear ANYTHING cotton if you can help it.
COTTON IS ROTTEN FOR RUNNING. Say it with me again, "COTTON IS ROTTEN FOR RUNNING." Cotton retains moisture and then chafes like hell.
Find some 90+% acrylic socks (I like Gold Toe MaxSpun at Target) and wear them inside-out. Why? Because the smooth side is the outside, the knots and seams are are the inside.
KEEP UP THE GOOD WORK!
