Dansko professional clog. Slip on. Denim burnished nubuck. Worn twice and then I got a different style. Size: 36 EU, 5.5-6 The Dansko Professional is the clog that launched a Comfort Revolution. Inside its iconic silhouette is a roomy reinforced toe box, an anatomically contoured PU midsole, an inner frame for stability and support, a padded instep collar, and a protective heel counter that allows the heel to move up and down freely while providing lateral stability. The anti-fatigue rocker bottom assists with forward motion while walking to add hours of comfortable support throughout your day.
