I've been shopping for cleats for football a lot. Nike's are way too narrow and run much smaller. Their quality is suspect too. Under Armour and Adidas aren't as bad with fit but still not comfortable. These Asics fir near perfectly right out of the box. there is a little bit of extra room near the toes but it still allows quick moves and cutting, which is a good thing for avoiding foot injuries. If you fit into New Balance shoes well these fit a little better, both of which tend to favor a little wider foot.
I wish these had detachable or removable cleats instead of the molded cleats. Speaking of which, I have not used these on the field yet. The cleat design does not have very narrow, sharp edged cleats. I'm not sure how this will translate on the field. I don't anticipate any issues though it may not have the same traction as some other cleats, but I think it will still be enough. The good thing is too much traction leads to injuries, so these might be a safer option for those try ing to stay safe. I ought to know btw as I have torn may ACL just from cutting too hard. I would have appreciated a shoe with a little more give than before.
Overall and excellent shoe. From the moment you put them on you can feel the better quality and fit compared to others. I would definitely suggest buying these to try on. It will be worth it if you have trouble finding a good shoe.
