Product description

The Kay PRO is a closed-toe clog built on a cork footbed with a suede-style lining, finished here in black PU coated leather. Two instep straps run through keepers and fasten with matching black buckles, so the hold across the forefoot can be adjusted; a heel strap can be buckled behind the heel or left out of use for slip-on wear. The footbed sits on a black treaded outsole with a blue stripe along the midsole, and the tread is moulded with EN ISO 20347:2022 OB SR and Birkenstock Professional markings. The coated upper has a smooth, sealed surface. Supplied in regular width in EU sizes 36 to 46.

Correct Fitting Size Conversion Product Care Shipping

Accurate measurements are key to finding your ideal shoe size and width. Follow these simple steps:

Measure Foot Length
Stand barefoot on a flat surface with your full weight evenly distributed. Using a ruler or tape measure, record the distance from the back of your heel to the tip of your longest toe (this may be your big toe or second toe).
Add Room for Comfort
Add 10 mm (≈ 3/8 inch) to your measured foot length. This extra space ensures natural movement and proper fit—this final number corresponds to the ideal footbed length for sizing.
Measure Foot Width
Measure across the widest part of your foot (typically the ball of the foot). Compare this width to the footbed dimensions for your calculated size. If your foot is narrower than the standard footbed width, consider a Narrow fit; otherwise, Regular is recommended.

Trying on a new pair: Follow the conversion guide to get the correct fitting

Breaking in a new pair: Allow your feet to adjust to your new shoes by limiting wear to just a few hours the first five to six times.

Protect the Upper: Apply a water- and stain-repellent spray suitable for your material (e.g., leather, suede, or nubuck) every few months or as needed to enhance durability and resistance.

Oiled leather protection: apply a Leather Conditioner to keep it supple

Cork protection: apply a Cork Sealer to maintain its integrity

Air Footbeds Regularly
Remove the footbeds (if removable) and let them air out in a well-ventilated, shaded area. This helps reduce moisture buildup and prevents odor.

Avoid Immersing Cork Models in Water
Cork footbeds and soles can warp, crack, or lose structural integrity when soaked. Never submerge your sandals—wipe clean with a damp (not wet) cloth only.

Keep Away from Extreme Heat
Prolonged exposure to high temperatures (e.g., direct sunlight, car interiors, radiators, or fireplaces) can dry out cork, crack the sole, or weaken adhesives.

Repair, Don’t Replace
Birkenstocks are built to last—and many components (soles, heels, straps, footbeds) are repairable. Visit an authorized repair service to extend the life of your footwear sustainably.
