what is the difference between the wool runners and tree runners? Is one more supportive than the other. Thanks!

Thank you for the fast response!

While the obvious difference is the material from which the two are created, the primary difference is the breathability of the fabrics. The wool runners are much warmer, and the tree runners can almost be thought of as a more summer-y version. I personally own the tree runners and love them, though I'm not sure which would be more supportive. I'm sure you will be allowed to try on both types to find which you like better. Hope I could help!
