In page American black bear:

"

Their claws are short and curved, being thickest at the base then tapering to a point, and most often black or grayish-brown in color. Claws from both hind and front legs are almost identical in length, though the curvature of foreclaws tends to be greater. The paws of the species are relatively large, with the forepaws measuring 2.1–5.3 incheslong (5.3–13.5 cm) by 2.1–5.6 incheswide (5.3–14.2 cm) and the hindpaws 2.8–8 inlong (7.1–20.3 cm) by 2.5–6.9 incheswide (6.4–17.5 cm),[5][6]: 76  which is proportionately larger than other medium-sized bear species, but markedly smaller than those of large adult brown bears, and even more so, polar bears. The soles of the feet are black or brownish and are naked, leathery and deeply wrinkled.[citation needed]
