I want to start running.

I was like you a year ago. I bought what I thought were good shoes. The brand I choose were Asics. They were very comfortable to wear and felt really good at first. After about 6 weeks they would break down and my legs would be killing me. I bought two new pairs and they did they same. I started to cuss the brand and finally went to a small mom and pop shoe store. I told them my issues and they were surprised because they are a good selling brand in their store. The nice lady took my feet measurements and asked my weight. She then asked me to run for her. Yes in the store. I didn't have to go far. She said the issue is your gate is unusual. The shoe I had choose was not the proper shoe. She went in the back and brought out three pairs of shoes and asked me to try each one. They all had a different feel and I selected one that felt really good. I now wear Saucony Shoes. My first pair is 3 months old and they feel as good as the day I bought them. I did pay about $20 more for them but the service was worth it. I now by my new ones at a local giant store at the cheaper price.

My advice is find a small store where commission doesn't matter. Explain to them what you are wanting to accomplish and they should be able to evaluate you and give you recommendations. If you don't feel satisfied go somewhere else. The good ones know what they are doing and you probably wont find them in a mall. My local one is in an old house.

Hope this helps.
