So, when I first got these, and put them on my son’s feet, I thought they were quite narrow. However, after a couple of wears, they must have stretched, and they now fit him well. He really likes them. They are clearly comfortable, and very light, and keep his feet nice and cool. And, they dry quickly. You’ve to watch the tongue a bit, as it can curl and fold round at the sides when he’s putting his feet in (not sure if that makes sense!). But, overall, we like these trainers, and my boy wears them lots. Would recommend!
