Icebug Pythos2 BUGrip
Here's what other sites are saying:
Icebug's Pythos2 BU Grip is an ideal racing shoe for recreational trail runners. Daily trainer for light, neutral runners. The low profile and flexibility gives you a good fell for terrain. A 3D flow-molded exo-skeleton cage supports and embraces the foot, retaining it closely over the midsole during aggressive maneuvers. The Pythos2 provides outstanding balance of trail feel and trail protection.
