Boston
Birkenstock Proprietary Last
US Men's Brannock: 9E
Birkenstock Proprietary Last: 9D
Roomy toe-box, narrow at the heel.
Stag Provisions
I chose the Boston clog because I wanted a durable leather slip on for both indoors and outdoors. I like hunting, camping and being outdoors in general and wanted a shoe to slip on quick if I'm popping out of a tent to... take care of business. Durability was a big factor, and I liked the fact the leather upper was thick enough to take on rough elements.
I used my brannock size when picking my size for these. They fit loose due to the nature of being a clog with a wide toe box.
I ordered them from an online retailer. Stag provisions was the name of the store. I had no issues with shipping or customer service.
