When did horses lose their toes?
Horses are the only creature in the animal kingdom to have a single toe – the hoof, which first evolved around five million years ago. Their side toes first shrunk in size, it appears, before disappearing altogether. It happened as horses evolved to become larger with legs allowing them to travel faster and further.
Why did horses have 4 toes?
What they found is that the extra toes in early horse ancestors were necessary; without the toes present to distribute the weight, the stress from running and jumping would be enough to fracture the big toe bone. As horses grew larger, however, the architecture of the big toe bone changed.
How many toes did the horse have?

It was an animal approximately the size of a fox (250–450 mm in height), with a relatively short head and neck and a springy, arched back.

Did horses have 5 fingers?
The oldest equines had five digits, and as the species evolved horses gradually dropped their digit number down to four, three, and then just one. Like their ancient ancestors, modern horses have the genes for five toes. But by the time they're born, today's equids are down to one toe per foot—the hoof.
Do horses feel pain in their hooves?
Since there are no nerve endings in the outer section of the hoof, a horse doesn't feel any pain when horseshoes are nailed on. Since their hooves continue to grow even with horseshoes on, a farrier will need to trim, adjust, and reset a horse's shoes on a regular basis.
