Since I have rather narrow feet, I think it's good that he's sitting pretty firmly or can be put together firmly, so I can not slip out, as with other shoes. However, it will quickly close with wider feet.
I have ordered the sneaker in 41 because sports shoes often turn out smaller and therefore I still have a little room with thicker socks. That was exactly right. Once impregnated with a dirt and water-repellent spray (in this color especially important), they are an every-day companion, even during the current rainy weather.
I have not regretted the purchase and would recommend the shoes.
