I own the Xero Shoes Z-Trail and they are fantastic. I bought them originally for camp on backpacking trips and water crossing. After wearing them a few times, these have become my go to footwear whenever I go out walking and on shorter hikes not involving boulders (read- PA section of AT).
The first two ones care now Cairns now. Should remove the option, as Cairns are already on the list. The whole list needs to be cleaned up, but overall, this drop needs to happen!
I've read on bedrock.com that you can send the trace of your foot and they'll cut it to your size with minimal or no additional charge. I'm on the fence to get Syncline or Cairns. Was waiting for the drop for a long time.
