“Croc sunburn” describes the damage or discoloration Crocs experience from direct sunlight or high temperatures. This common issue affects many owners, as these comfortable clogs are often worn outdoors. Understanding this material degradation is important for maintaining your footwear’s appearance and longevity.
Understanding Crocs and Sun Damage
Crocs footwear is crafted from Croslite™, a unique closed-cell resin primarily composed of ethylene-vinyl acetate (EVA). While Croslite provides signature comfort, lightweight feel, and odor resistance, its properties also make it vulnerable to specific environmental conditions.
Prolonged exposure to intense ultraviolet (UV) radiation and high temperatures significantly affects this resin. The EVA polymer within Croslite degrades and shrinks from sunlight and heat. This thermal and UV degradation impacts the shoe’s form and function, often causing noticeable shrinking.
In addition to shrinking, the material can also warp, losing its original shape and becoming stiff or uneven. Discoloration, such as fading in vibrant hues or yellowing on lighter-colored Crocs, is another common symptom. These changes result from the material’s reaction to heat and light, altering its cellular structure and integrity.
Preventing Sun Damage
Protecting Crocs from sun damage involves mindful storage and usage. Storing them indoors, in a cool, shaded area like a closet or shoe rack away from windows, shields them from direct sunlight and extreme temperatures. This prevents thermal stress, extending their life.
Avoid leaving Crocs in hot environments where temperatures can rapidly escalate. This includes sunny patios, near heat sources like vents or radiators, or especially inside hot cars. A vehicle’s enclosed space can trap intense heat, causing rapid and severe shrinkage or deformation.
While Crocs are suitable for outdoor activities, be mindful of prolonged static exposure. Leaving them by a swimming pool all day or on a sunny deck exposes them to continuous intense UV radiation and heat. General cleaning with mild soap and water helps maintain integrity, but preventing direct thermal and UV exposure remains the primary focus.
Addressing Sun Damaged Crocs
When Crocs experience sun damage, the extent determines the potential for restoration. Severe shrinking or warping, where the shoe’s structure is significantly compromised, is often irreversible. Permanent structural changes make replacement the most practical solution for comfort and safety.
For minor shrinking, Croslite can be made malleable through controlled heat for reshaping. Methods include submerging them in boiling water, tossing them in a clothes dryer with damp towels, or using a hair dryer. Once softened, wearing them with thick socks while they cool can help stretch them back to a more comfortable fit. Proceed with caution to avoid burns.
Minor discoloration, such as slight fading or yellowing, may improve with thorough cleaning. Mild soap and water can remove surface grime. Some owners find success with a baking soda paste or a magic eraser for stubborn marks, though UV-induced color changes often do not fully revert. Extensive color changes from UV exposure are typically permanent. If comfort or structural integrity is compromised beyond repair, replacing the footwear is the most effective choice.
