I wish I had purchased Wildlings sooner! I have been aware of them for some time (thanks to Anya's Reviews) but was hesitant due to the unusual sole structure. They're great! I like the flexibility, and there was no reason for concern. The quilted insert is surprisingly comfortable without changing the ground feel. I highly recommend Wildling, and cannot wait for a reasonable reason to purchase additional styles. Note about sizing: they run very true to sizing guides, so if you are used to "sizing up" when in doubt be careful -- you probably won't need to do that with Wildling.
