A close-up, downward-angle photograph captures a human right heel in Givat Shmuel, Israel, prominently displaying a large, fluid-filled blister. The blister, approximately 3-4 cm in length and pink to reddish in color, is situated on the lateral aspect of the heel. The surrounding skin is light-toned with fine hair visible on the lower calf. To the left, a portion of a blue denim-clad leg is visible. In the background, on a light-colored tiled floor, a light brown sandal with a darker strap is partially visible, along with a small, clear plastic cup containing grey particulate matter. Shadows are cast across the floor, suggesting ambient indoor lighting.
