I bought these brand new! I wore them only a handful of times. These shoes are in excellent condition! When I wore them, I ALWAYS wore socks. They are almost like new! Insoles removable (See pictures) In the pictures near the Veja, it appears as if there is a stain....it is not a stain. This is under the clear part of the shoe. It is the same on both sides. The pictures also look like there is a stair or something at the shoe strings. This is an air hole built in the shoe. Very little wear on the back of the sole. (See pictures) Named after one of the world's fastest fish, Veja Marlin sneakers are made for road running and work with your natural movements to give the support you need. Made in Brazil, they have breathable V-knit uppers and flexible tech-mesh linings, both made from recycled plastic bottles. The shock-absorbing L-Foam cushioning provides 80% energy return, while the bouncy soles offer plenty of grip on tarmac or grass.. Description The Marlin is a minimalist and lightweight running, which emphasizes performance. Its intermediate sole provides quick sensations and comfort in a durable set, ideal for intense outings. **Description taken from website** tags : preppy, walk, run, jog, chunky, work, exercise, gym, nurse, clinical, hospital
