US Army bans Five Fingers!
There are a variety of minimalist running shoes available for purchase and wear. Effective immediately, only those shoes that accommodate all five toes in one compartment are authorized for wear. Those shoes that feature five separate, individual compartments for the toes detract from a professional military image and are prohibited for wear with the IPFU or when conducting physical training in military formation.
I'd say we surrendered the war for "professional military image" when our soldiers' uniforms started looking more like pajamas, but what do I know?
