New Running Shoes...Already?

Well, my Nike Pegasus 25+ running shoes have about 210 miles on them. Yikes, how did I rack up the miles so fast? Well, I'm now up to the mid 20s for mileage each week, so yes, the numbers do add up pretty quickly. While they are still fine, I am finding that I'm getting a little more ankle and knee pain more frequently now. Not sure if that's because I'm running so much, or that the shoes are starting to lose their cushion. Probably a little of both. Plus, with another week until my half marathon, I'll be pushing 350 miles by race day, and that may be pushing it for having a smooth, ache free race. So, I went to the local running store and got a pair of Mizuno Wave Rider 12s. They recently won the Runners World editor's choice award, and are definitely a quality shoe. I went with size 12, although the running store wanted me to buy a 12 1/2, but they just felt too big and loose. I've had no problems with my feet at all in my Nike Pegasus 2007 or 25+ in size 12, so I'm not going to change now. We'll see how they feel when running. They sure felt awesome when I tried them on. I could have gotten them for a few $$ cheaper online, but decided to give the LRS some love instead.
