Some deformities do take time to be noticeable, but the most significant ones are more immediately visible. Infants can be born with a variety of foot deformities, most all of which are correctable. These can include rotational deformities, such as clubfoot (rotation of the foot inward) or congenital calcaneovalgus/vertical talus (rotation of the foot far outward). Both of these deformities need immediate correction to prevent future debilitation, and are generally successfully cured with casting and bracing or early corrective surgery to release tight ligaments and return the foot to a proper position. Extra toes are sometimes present, which can be removed later on for cosmetic appeal or to ensure proper shoe fitting. Shortly after birth, a condition called metatarsus adductus can be seen in which the foot takes on a c-shape, as the long metatarsal bones are rotated inward too far. This can be corrected with casting, bracing, special shoes, or surgery if the deformity is not addressed until later on in childhood. Some level of this deformity can be considered normal, although if it is noticeable externally it is likely in the abnormal range.
Leather is processed to the required softness. Every item of leather demands its own level of softness. Softness of the leather differs from product to product such as Leather Shoe Soles, Leather Saddles and Leather Cycle Seats, Leather belts for industrial, animal and human use, Footwear, Shoes, Sandals and Chappals, Leather Boxes, Bowls and Luggage Bags, Leather pouches, wallets and Ladies Hand Bags, Leather cases for several industrial instruments, gift items.

Finally the processed leather is measured in Square Feet (SqFt) and DeciMetres (DCM). To have an accurate measurement, the leather is placed flat, fully stretched over the conveyor body of a measuring machine and passed through a controlled unit which electronically displays the measurement of the leather.

Once the child begins to walk, certain deformities can be seen that were not noticeable before. This includes heightened inward rotation of one of the legs, or less commonly heightened outward rotation. Also called in-toeing, this condition is not unusual. Most cases are simply due to uneven leg muscle development, and will resolve on their own. Some cases, however, are due to a deformity of the hip, the thigh bone, or the lower leg bone, and need either aggressive therapy and bracing to reduce the deformity, or surgery to de-rotate the involved bone.As the child begins to walk more, one concern many parents have is whether or not their child is flat-footed. All infants with normal foot structure have flat, flexible feet. The arch structure slowly develops as the foot strengthens. In the beginning, children walk flat-footed, and slowly reach normal arch structure as they begin to walk with a normal heel-to-toe walking pattern by age four or five. If the foot seems excessively flat in the beginning, or if the arch is not forming, then the child may be flat-footed.
Modern Industries use large drums made of Teak wood (Sagwan), rotatable by electric motors for such tanning, softening and coloring process of the leather. The leather processed by these methods then put on hangars in a shaded place to get dried. The dried leather passes through various shaving, splitting, stretching, and polishing process till it become fully soft to the required level, color, and thickness.
