The detail in these feet is amazing. The ape feet were constructed for the film using a pair of a mens size 9 scuba boots with very realistic ape toes glued onto it. Around the top is 'ape hair' to give it a very real look. These appear to be feet that did not need to fit inside a military boot but possibly were worn without it. (but I cannot be sure of this though) These feet were used in the film and I include the proof of such I received from 'Studio Props'
