Wow you sound like you know what you're talking about. I start with two bras. A regular one and then a sports bra that I get in three packs from Walmart. I think the combo is as good or better than the expensive running bras sold in sports stores. Then I wore long sleeve wicking fabric base layer. On top I wore an Under Armor cold gear hoodie and jogger pants. I wore wool hiking socks, polar tech watch cap, and I lightweight infinity scarf from Walgreens. I like the thin fabric because I can breath through it and it blocks wind. I also wore mittens, and a garmin gps forerunner 35. I use my watch to watch my pace and time. I also wear a running belt for my phone and keys. I try to keep my pace about 3.2 mph. I can't worry about people passing me because I am running my own race. If I keep around 3.2 mph then I can keep going with jogging and not start walking. I wear New Balance 840 with an insert. I can buy 7d with New Balance and they are deep enough for aftermarket orthodic inserts. I try to get an insert with support and cushioning. Inserts are very important for my running. I go to shoe, foot professionals to help me select shoes and inserts. I knew I couldn't do that by myself. I also wen to the mayo sports medicine department for a check up and some training sessions to make sure that I could jog safely.
