Original vintage wooden shower shoes / sandals. Made by Sinclair Wood Product in NJ. Marked size M. They measure about 10 3/4" long - which is approximately a US men's shoe size 9-10 - most shoe size charts put it in the size 9 1/2 range +/- a half size (EU size 43-44) and about 3 5/8" across the ball of the foot. These were found in a Red Cross ditty bag / apron. They are in decent, used condition. There is wear on the bottoms. The fabric is in good condition. There is a little rust on the nails. Still wearable.
