The Nike Quest 6 has been a great fit right out of the box. The sizing felt true, and the shoe wrapped comfortably without feeling tight or loose. It was easy to get a secure, natural fit from the first wear. Quality is solid for everyday use. The materials feel well put together, and the shoe holds up nicely for walking and light running. It feels dependable and comfortable for regular wear. What really stood out was the value. The price was much better than what I saw in retail stores, especially for a Nike shoe that performs this well. It’s an easy way to get a reliable running shoe without paying full store pricing. Overall, it’s a comfortable, well-made shoe that delivers a lot for the cost.

Good for training

Super cool looking, comfy, lightweight, good price and great for running. Im using a size 9.5/ 27.5cm and it fits perfect, with half an inch of space for my toes.

So comfy

Solid solid solid shoe. The value for the money you spend is quick to be noticed. Working in a dental office, I’m on my feet a lot and all of these brands who say they were made by nurses blah blah blah are liars. These were finally the shoes that didn’t make my ankles or feet sore. They take shock absorption so smoothly, and allow me to feel supported and comfortable. Wearing them all day isn’t a chore and honestly made me realize I was less grumpy because I was much more comfortable
