I've been having problems with my achilles for a while and I've read here and other places that heel lifts help with AT. I'm wondering if this is something that my local running store can set me up with, or if I need to be fitted by my doctor or PT. I know that I don't need to buy them through a healthcare provider, but I'm wondering if I should at least consult with one to get an idea of what amount of lift I should use, what brand to buy, etc. The guys at my local running store are pretty knowledgeable, so if I don't see a doctor I won't be stuck trying to get advice from the sports department cashier at Wal-Mart or anything like that.
