How does the 'wedge' in the name differ in heel shape from regular flip-flops?
Flip-flops are often thought of as flat shoes without heels, so one might wonder what kind of shape the wedge in the product name refers to. Shoppers also look into how the heel height and sole structure feel when walking.
The wedge is a shape where the sole and heel seamlessly connect into one piece, featuring a 4cm-high heel complemented by a slip-reducing rubber outsole.
Wedge means wedge-shaped, referring to a heel style that thickly supports the entire sole of the foot in a continuous line, unlike regular heels where only the back heel is raised. Because the boundary between the heel and the sole connects continuously as one piece, it evenly distributes the weight borne by the sole of the foot.
It has a thick feel. CLEAN WEDGE FLIP-FLOPS / BLACK has a heel height of 4cm based on size 250[1]. Unlike regular thin-soled slippers, it relieves shock coming up from the ground; based on the same size, the ball width is 9.5cm, the instep circumference is 10cm, and the foot length is 25.8cm[2].
Polyurethane is used for the upper and lining that wrap around the instep, as well as the midsole touched by the sole of the foot[3]. The outsole in direct contact with the ground is made of Rubber material[4], and a non-slip outsole that reduces slipping has been added[5]. While providing heel height, it also secures ground grip to help keep your feet from slipping when walking.
