Kevin's KSO Vibram Five Fingers and a Pregnant Lori gets Comfy in Classics

In the mailbag from Kevin (KoffeeKev in the birthday shoes / five fingers forum) comes a few photos of black KSO Vibram five fingers, grey KSOs and Injinji socks, as well as a couple shots of Kevin's pregnant sister-in-law Lori, who is wearing the lilac five finger Classics.  Here's what Kevin had to say about the shots:

[My sister-in-law] Lori loves her shoes and wanted a pair from the first time she saw mine ... so I finally bought her a pair. Bob is my wife's brother and Lori is his wife ... She really does love them.

The wearing out of my black kso's is all over. The straps are deteriorating near the loops on the sides. The velcro is starting to fall apart. The soles behind my outer toes (pinky and ring) are worn smooth. This is all good because the shoes get thinner and more comfortable with each passing day. I will be disappointed when they finally blow through. The new kso's seem much more rigid and thick. I don't know if it's my imagination or someting to do with the gray rubber compound. We'll see as they break in.

I think I bought the first pair about this time last year and the kso's a couple of months later. I wore them all through the winter, not to work but just about everywhere else. The only weather I didn't take them out in was wet snow and puddles and long outdoor outings. I'm not a winter sportsman so it wasn't a problem. I did get caught a couple of times with soaked, frozen feet. Not fun.

Kevin also posted in the forum that both of his black KSOs weigh a full ounce less than when he bought them due to the lost rubber from wear-and-tear.

My wife is about 32 weeks pregnant and has had a bit of foot swelling, so I've been trying to figure out if VFFs would be a good way to make her feet more comfortable (And thus be the tipping point to get her to finally get some!). Thus, I asked Kevin if Lori had experienced any of the same, but she hadn't (You're lucky, Lori!).  My worry on the Classics and swollen feet would be that the elastic would feel tight and uncomfortable.

Any other pregnant VFFers out there care to opine on swelling feet and Vibrams?
