The metatarsals are in the middle/forefront area of your feet. Technically they are considered the forefoot but when you look down at your foot, they are close to the middle. There are five metatarsal bones. Each one leads to a toe. Now if by chance you had six toes, it’s possible that you may also have six metatarsal bones. Since joints form when two bones meet, you’ll have 10 different metatarsal joints, five that connect with the toes and five that connect with the metatarsal bones (cuboids and cuneiform’s). Tendons insert onto the metatarsal bones.
Metatarsal insoles would be insoles that support the metatarsal bones of the feet. These are cushioning type of insoles that are especially important for those who have problems with the metatarsal bones of ball of foot pain.
For example, there are nerves that run between the metatarsals. If shoes are too tight, guess what happens? The metatarsals are scrunched together and those small nerves between the metatarsals are scrunched, too. You could get pain from this.
Those nerves cry out in pain and that’s what you get – a lot of pain with every step. It’s a burning sensation of pain in many cases. If you add metatarsal insoles into your shoes, you’ll find that the pain is relieved.
The pain relief is due to the proper support of the foot – the metatarsals. There’s another condition where adding metatarsal insoles to your shoes will also make a big difference. It’s called sesamoiditis. On the big toe, there are very small sesamoid bones that help cushion and protect your feet as you walk. If those small sesamoid bones get inflamed for whatever reason, you’ll have pain in the area of the inflamed sesamoid bones. However, metatarsal insoles will speed up recovery by supporting your feet properly and provided some extra cushion.
Another few conditions that necessitate the use of metatarsal insoles include conditions where the ball of the foot hurts, Morton’s neuroma and when there’s pain in the forefoot.
