- Sports bras, unless they're new with tags. Most of the time they're usually stretched out to the point where they're no longer supportive. It can make a run very uncomfortable!
- Running shoes. Only rarely do I ever find a pair of shoes that are practically new, and I have yet to find a pair of running shoes that didn't have worn down treads. Wearing your own worn down running shoes can lead to injuries. If you must get shoes on a budget, running stores typically have clearance sales a few times throughout the year and some will even sell shoes that were returned. But if you walk into a discount retailer, don't expect to get quality similar to high end running shoes.
- Socks. Yes, I have seen socks at thrift shops. That's another place I draw the line. Make the investment in a good pair of socks and they'll last a long time. (My personal favorites are balegas!) Many running stores will have sales on them at different times of the year and at running expos before a race. If you don't want to shell out $10-14 for a pair of socks, there are others out there that are less expensive. It's just a matter of trying a bunch of different kinds and finding out what you like!
What are some great deals that you've found while out thrift shopping? Are there any items that you will just NOT buy at a thrift store?
