Pretty cool, and they all look pristine. That is definitely a pretty cool passion.
I never really got into collecting shoes, always putting my extra money to either keeping my old Blazer running or the Honda.
On my list
Numerous pairs of flip flops (the good expensive kind, no rubber or plastic ones)
Work boots
Grass cutting boots (former work boots)
My Asics running shoes
a pair of Nikes (all white)
Pair of beat up DC shoes
and 2 pairs of FILA Skel-e-toes (black running, and blue water ones, very comfortable)
I can take pics if anyone wants but they aint as pretty as yours are.
