Did you try them? With running shoes it's important that they give you support in the right places and that they ensure that you don't take too much pressure on your knees. I went to a store here and was consulted for over an hour and we tried about 7/8 different pairs of shoes. I tried different brands, models and sizes to ensure I found the right one for me. Now I buy those shoes over the internet for half the price, but that first consultation was well worth it!
