Shoes can make or break your workout routine. The right pair will provide the support you need for the type of activity you do. The wrong shoes can lead to blisters, sprained ankles, shin splints, and a host of other problems. Consider the shoes you are using now. Do they fit well? Do they offer the right kind of support? Are they in good condition? Are they appropriate for the activity? If not, it may be time for a new pair.
