They are not Chuck Taylors. These are the CX-PRO-250 model according to my book.
There is no ankle patch. They also have the chevrons on the sides and padded collars. The tread has stars so not the usual Converse tread. They have been worn but very very little.
The tread has a tiny bit of wear at the rears. They were made in USA.
They are 12.2 from toe to heel. The rubber is still flexible. These are very collectible and will only increase in value in years to come.I have been collecting Chuck Taylors for many years and have about 400 pairs in my collection shown in the pictures.
