This listing is for a pair of preloved Birkenstock Boston shearling clogs in size UK 4 and EU 37. 
These stylish and comfortable shoes feature a low top design with a round toe, slip-on closure, shearling lining and a flat heel. 
The suede upper and shearling lining provide a cosy and sustainable option for casual wear. 
mauve colour ( slightly lighter than the photos show) 
Small stain on right foot ( which is reflected in the price)
I wear Birkenstock Boston style a lot and found these ran a little more narrow, possibly because of the shearling lining - so I would class them as narrow fitting.
