I live in Spain. When i went to a sporting goods store to buy sneakers and saw something I liked they brought me one sneaker to try on. I asked to try on the other one so they took the sneaker I tried on back and brought out the other one. I liked it so they gave me a ticket to bring to the checkout. After I paid they gave me the sneakers. No shoplifting problem there.
All the new shoe stores here are ‘self serve’. Skechers,
Famous Footwear, Designer Shoe Wearhouse, etc. On the display rack is a shoe and then underneath are the boxes of shoes in different sizes. You find the shoe you want from the display then search underneath to see if they have your size. Makes theft very easy even though it cuts down on the number of employees working (usually only 2-3) per store.
Some convenience stores in certain neighborhoods keep all the goods behind bulletproof glass. Pay first, clerk puts item in a drawer & slides it out.
Very safe!
No more issues with customers tripping because they were hobbled by laces tying left shoe to right shoe.
Steal the right shoe on Monday, go back and steal the left shoe on Tuesday. Problem solved!
