This is an Onitsuka Tiger Marathon from the late 1960s to early 1970s.
It's a model originally exported to the US at the time.
It's highly likely this pair was imported and sold by BRS.
These sneakers have been stored for many years.
They show signs of wear, with overall dirt and scuffs, and the heels are slightly misshapen. The outsoles have some wear but no hardening.
Otherwise, they are in perfect condition.
If you are familiar with vintage sneakers, you should be able to wear them without any issues.
Size... Outsole total length approx. 29.5cm (equivalent to 28.0–28.5cm)
