Shoe Anatomy

Shoe Apron
An apron is a piece of leather material that covers the top of the vamp around the perimeter, almost like an apron that you might wear.
Tricker's Eyelet on Boot
An eyelet is a hole in the upper of a shoe or boot through which the laces are threaded. Eyelets are added in the closing room of our factory and are added at the same time as patterning and rivets.
Goodyear Welting
In a Goodyear welt, the outer sole is sewn to the welt, the cavity between the welt and insole is then filled with a layer of cork, which moulds to the wearer’s foot, providing insulation and comfort. The cork is then covered with a leather mid-sole for protection. 
Half Bellows Tongue Shoe anatomy
In a traditional bellows tongue, the tongue of the boot is attached directly to the upper along the opening where the laces run, rather than being a mostly free-floating piece of material attached only at the bottom, as in most footwear.
Trickers Insole of shoe
The material that is inside of a shoe and is in contact with the foot when the shoe is being worn. The woven rib on the insole is also used to secure the upper as it is connected with small nails and staples to hold the shoe together until the welt is attached. 
Shoe Lining Trickers
The lining of a shoe surrounds the foot from all sides and its job is to keep your foot warm and dry whilst optimally regulating the moisture balance inside the shoe.
Midsole
The mid-sole - also known as the ’through’ - is a mostly piece of leather that is placed over the layer of cork which is in the cavity between the welt and insole.
Shoe Lining Trickers
Sock lining is the inner part of the footwear that covers the insole (footbed) of our footwear. You touch this part with your foot when wearing shoes.
Shoe Upper
The upper is the part of the shoe that covers the toes, the top, sides and back of the heel. Uppers are normally made from several parts of material, usually leather or suede, which are stitched together by expert craftspeople.
welt
The welt is a leather strip that joins the insole to the upper to which the sole is subsequently attached by stitching. Because welted shoes are sewn together rather than glued, skilled craftsmen can dismantle, repair and refurbish them. 
Wooden Shank
The shank is an internal part of the shoe which goes between the insole and outsole and provides stability to the shoe.
