A nice present came in the mail for me yesterday. Merrell sent me a couple pairs of the Sonic, a new shoe in their Barefoot lineup. The major difference between these and the Trail Glove, is the upper material. Instead of the mesh the the Trail Glove is made of, it is a thin solid nylon. This is good, especially when running on trails sockless. Dirt and small stones were able to get into the Trail Glove. That could get uncomfortable. That should not be a problem with the Sonic.
I have not gone running in the Sonic yet. Tomorrow should be a wet trail run in them. I will report the results.
