Online shopping - how to get the perfect fit?
WBD Work Boot Size Chart
STEP 1 - Foot length
The best way to do this is to stand barefoot on a piece of paper and mark where your longest toe ends. 
Measure your foot length in millimetres from the back of your heel to the tip of your big toe 
Work Boot Size Chart
Repeat this step with both feet, and use the largest measurement to calculate your size from the chart above. 
STEP 2 - Need some width?
For those with a wider foot, we suggest you select a half size up. 
STEP 3 - Trying them on!
When you receive your boots, try them on while you’re wearing the socks or stockings you will typically wear with your boots.
Ensure you’re standing up, and try them on a carpeted surface so the bottom of the boots are protected.
