Alright, it's my turn to have a question for the experts... what to do about DRASTICALLY changing my shoes at this point?
I've run in the Nike Pegasus for about 2 years, now. This includes training for the Goofy last year - no problems, no injury, no pain. Before that it was the Nike Max Moto, and the Asics Nimbus... these are all very neutral shoes and the Nikes are particularly soft. I was fitted for them at a running store and the employee even made the comment, "wow, you don't pronate at all!" Around month 5 of my pregnancy (while training for a half marathon), I started having arch pain in my left foot. I figured it was just all part of running while pregnant and sucked it up. This arch pain has been getting worse over the last few months, after taking 2.5 months off running while VERY pregnant and after delivery, and it finally dawned on me over the weekend that it was probably my shoes.
I went into Road Runner Sports and did the barefoot running test on the treadmill... and it wasn't pretty. I now pronate severely in my left foot and my arch has dropped significantly. The guy who was helping me at the store (and who was AWESOME!) said that I could even wear a motion control shoe on that foot, but it would be too much for my right foot. Anyway, I tried a few stability plus shoes and we did the treadmill test a few more times before finding a winner. I went from the Pegasus (one of the softest shoes out there) to the Mizuno Alchemy (a very firm shoe that sacrifices cushioning for stability). I also did buy the heat-molded custom insoles, hoping they'll help with my sagging arches.
So, can I just put on the new shoes and go back to training, or am I going to need a break-in period? I've been wearing very cushioned shoes for years and now I'm going to a very stiff shoe. It's pretty late in the game, but my problems were just getting worse in the wrong shoes. Help, please?
