Trainers don’t stretch, but through frequent wear they do mould to fit the shape of your foot. So, if your trainers should feel a little tight, we would recommend spritzing them with a little shoe stretching spray and wearing them around the house to encourage a better fit. If your trainers are still too tight try filling your trainers with clean socks so that they are full, leave over night and they should feel a little looser in the morning.
