Remember the future? The Spiridon Cage 2 is uncut millennium style at its finest, appearing just as it did on the day it launched in 2003. The shoe's name comes from the enlarged, "caged" air bag on the heel, which not only flexes that early 2000's vibe, but gives the kind of comfy ride you've come to expect from Zoom Air. This Metallic Silver iteration shows off the shoe's unique patterning and looks like it belongs on a fashion runway in space.
