Coldwater Creek http://www.coldwatercreek is where I purchase my shoes. The last pair that I bought was a pair of New Balance running shoes with the pink breast cancer logo on them. I chose them out of one of Coldwater Creek's catalogs because I know that they send a good portion of their proceeds to the stated fund.
Coldwater Creek is also an excellent place to shop for shoes since it offers just the shoe you are looking for at the time of year you are looking for it in.
They have outdoorsy shoes for hiking.
They have cute flats to enhance your flirty skirt.
They have high heels to bring attention to your elegant legs and make everyone take notice.
They have cuddly slippers to just snuggle into at the end of the day.
The best thing about shopping at "The Creek" is you can do it at one of their many stores, online, or over the phone. Their customer service is wonderful; especially when shopping for shoes. The person on the other side of the phone will always tell you if you need to "go up or go down" a size on the particular shoe you are ordering.
Their return policy is one of the best I have ever run across. They make shopping with them a pleasure.
