I've recently come tot he conclusion that sneakers need to be replaced regularly. Sounds like common sense but remember I'm not a "sports" person. I've been wearing the same adidas sambas for about 3 years. They've stretched two sizes since I bought them. My friend who is into running says every 300 miles you should replace sneakers (I may have remembered that wrong). Oops.
Now that I've been searching for sneakers I'm between two types, which should I get.
1. Basketball Sneakers: Good for my ankles, super fresh. Some people call them high tops. http://www.zappos.com/supra-vaider-womens-purple-lavender
2. They're probably most practical, since I'm usually running or biking when I wear sneakers.
