She most likely has 'Grass rings' from being on the rich lush grass for 1-3
Yes, if there are no other symptoms, she may not have laminitis currently, but the 'grass rings' are an indication of a recent event. I don't get what you mean about located near the toe(if there is also 'rotation', rings can converge at the toes?), but it appears the rings do go right around her feet in the pics, as well as being present in the same region on every foot, rather than just in a small area which could indicate injury/abscess. The lush grass can cause laminitis due to it being particularly rich, or the horse being particularly sensitive to it, for eg. If she is insulin resistant. While if the horse has been overweight long term, insulin resistance is a likely problem, considering the 'event' appears short lived, I'd guess perhaps there was growing conditions that caused the grass to be extra sweet at that time, or you grazed her on much richer stuff than usual, it was recently fertilised or some such.
While it does appear she needs a diet, it's imperative you don't leave her to go hungry. The way a horse's digestive system works, it needs small amounts of feed going through near constantly. Therefore you still need to provide free access or little & often feedings of hay/low cal forage.
