Dansko shoes should always be bought a size bigger. i returned a size 39 and got a 40. HUGE difference. Being on my feet all day in the laboratory doesnt fatigue my knees and lower back anymore. they are expensive for work shoes, but they last forever and i can see myself ever working in tennis shoes again. plus i can spill blood or acid or formaldehyde and just wipe and decontaminate these sucks in a flash. i chose this scratchy colored pattern. i have gotten several compliments on them.
