|Inexpensive footwear for wearing on holiday on the beach or in sunny weather.|
These shoes appear to be made without a "last" which is the wooden mould used to shape a shoe.
The upper and sole seem to be joined by "blanket stitch" in a thick contrasting thread
The pair on the left seem to have no heel; I am unsure about those on the right.
Photo on the left is taken in Blackpool that on the right is Southend-on-sea
I would imagine these sandals would be a holiday purchase,bought for the holiday or at the seaside.
