What ever your favorite activity is, running, biking, Pilates, weight lifting or walking, buying a cross trainer is a helpful choice in supporting your performance and experiencing a better longevity.
One main consideration is support. Then you can add other considerations to the mix. Womens cross training shoes cover a mix of needs and details, with no one thing to an extreme. Although if you plan to run quite a bit, you may want to consider buying a proper running shoe.
Like many other sports shoes, you want to pick your womens cross training shoe size by giving yourself a little bit of room between the front of your toes and the front of the shoe. The rule of thumb is to leave half an inch of free space at the front of your foot, to the end of the shoe. Some also find it a practical idea to keep socks for the use of these shoes only. Some people like to buy new socks when they buy their new shoes. You may want to consider this thought as well.
