Loving my B2R's more than ever.
I'll reiterate the construction of these shoes is superior. No de-bonding. No stitching issues. The upper material is very resilient and comfortable on the foot.
The soles are wearing well. The center and right images below show the wear. A little wear on the outside of the forefoot and moderate wear in the center of the forefoot. So, I'm thinking these soles will go maybe 800-1000 miles. We shall see...
I also took Eric's advice and ran the last 125 miles with no socks, and I'm happy to report my normally very sensitive feet have had little issue. Had a small blister pop up on my left heel during a 10 mile run. This was a 90+ degree day, lots of sweat (a perfect day for blisters...heat, friction, moisture). On subsequent runs I just tied my shoe a little tighter and no recurrence. On the same run my right foot formed a slight linear blister on my arch at the interface between the insert and shoe upper. I've been running without the inserts and the feel is just fine.
I believe I'll be ordering a half size smaller for my next pair. I normally go for a half size big, but I now appreciate Eric's comments on snug fit.
Next update at around 400 miles...
