Just wanted to post an update...
First, I took a pair of those wooden thingies that you put inside your shoes to hold their shape (what ARE they called?) and SHOVED them deep into the toes of my Reva's. Left them there for several days.
Then, yesterday, I was at the hair salon and ran into a friend wearing them in silver. I asked her how they fit, what size she wore, etc. and she let me try hers on. We both wear an 8.5 or a 9, and hers were a 9. I was shocked when I tried hers on and they felt soft and cushy! No pressure, no discomfort at all.
So, I tried mine on this morning and they definitely had more "give" to them than they did before. I even wore them to work (1/2-day.) I had to take them off when I came home, but wearing them 1/2 a day is WAY better than having sit in the closet looking lovely.
So... I've come to 2 conclusions:
1. Some pairs are just softer and looser than others.
2. You CAN stretch them out somewhat. Hopefully, mine will continue to loosen up (with or without the help of my friendly neighborhood shoe repair guy.)
