I think I may have a problem...

Anyway, here is my current collection of 'barefoot' sandals, arranged in descending order by stack height/ground feel.

Happy to share my experience if you have questions about any of these. Otherwise, thanks for stopping by to witness my financial irresponsibility and my addiction to collecting things.

Top Row: 

* Earth Runners Primal - 7.5mm 
* Deliberate Life Designs Camp Sandal - 7mm
* Shamma Cruzers - 7mm
* Zuzu Flow - 6.8mm
* Xero Aqua Cloud - 6.5mm

Second Row:

* Wildsole Hare - Advertised as 4mm, but really more like 6.5
* Shamma Legend - 6mm
* Shamma Warrior - 6mm
* Sole Runner Neso - Advertised as 2.5mm, but they're only counting the actual rubber.  With the midsole and footbed, it's just a hair thinner than my Shammas
* Panta Parnosas - 5.8mm

Third Row: 

* Xero Z-Trek - 5.5mm
* Xero Genesis - 5mm
* Luna Equus 2.0 - 5mm
* Toetem OSEM Vapor - 4.5mm
* Xero DIY #1 - 4mm.  I added toe loops and back straps in attempt to make a thinner version of the standard Genesis.

Bottom Row:

* Xero DIY #2 - 4mm
* Chala Classic First Edition - 3.9mm
* Chala Classic Custom with 'Berlin Edition' footbed - 3.3mm
* Geniale Sandale - 2.9mm
* Fullsoul Runningpad - 2.5mm (est)
