Minimal shoes have been an increasingly popular option for different types of runners and athletes. While the idea of a shoe that allows an athlete to improve their natural biomechanics sounds like a great idea, there are more to minimal shoes than what meets the eye.
What are they?
A minimal shoe is a shoe that provides significantly less support than a traditional running shoe. The support in the heel, midfoot and arch is significantly less, which depending on body mechanics, can be a good or bad thing. With good running mechanics, having less support/cushion can be beneficial since it cuts down on unnecessary weight. Bad mechanics, however, can lead to injury because there is not as much supportive cushion to help correct inefficient running form. Because minimal shoes have less support, they are very light and generally form around the foot.
After prominent Olympic star Zola Budd became famous for running/training barefoot, and Christopher McDougall’s national bestseller novel “Born to Run,” the interest for minimal shoes arose. Nike released the first “Free-Runs” in 2004, then two years later Vibram came out with the first “Five Finger” shoes. The drop in minimal shoes between the heel and forefoot is anywhere from 4 mm to 0 mm, as opposed to a traditional shoe that is around 12 mm. A minimal running shoe can help an athlete run more naturally by utilizing a more efficient foot strike, cadence and gait.
Different Types of Minimal Shoes
Just like regular shoes, minimal shoes vary from each other. Each brand/model has its own unique characteristics. For example the Merrell Trail Glove is a shoe that has a 0 mm drop (the height difference between the heel and forefoot). This means the shoe has no slope, and has the least amount of support. Another example would be the New Balance Minimus which also has a 0 drop. A level up from that would be a shoe with a 4 mm drop, such as the Saucony Kinvara or the Brooks PureCadence. These shoes have a bit more support than a zero drop shoe.
Some other minimal shoes are:
- Merrell Road Glove - 0 mm drop
- Merrell Dash Glove - 0 mm drop
- Merrell Pace Glove - 0 mm drop
- Merrell Bare Access - 0 mm drop
- Vibram 5 Fingers - 0 mm drop
- New Balance Minimus - 0 mm drop
- Saucony Hattori - 0 mm drop
- Brooks PureCadence - 4 mm drop
- Brooks PureGrit - 4 mm drop
- Brooks PureConnect - 4 mm drop
- Brooks PureFlow - 4 mm drop
- Saucony Mirage - 4 mm drop
- Saucony Kinvara - 4 mm drop
- Nike Free Run 4.0 v3 - 4 mm drop
Who can wear these shoes?
Some steps should be taken before going minimal. Going to your local specialty running store would be a good idea, since they can provide more information in regards to your own foot type and unique running style. Not everyone’s foot type is an ideal candidate for a minimal shoe. Minimal shoes are most suitable for people who tend to have a “normal” foot type, where the alignment of the foot is straight, or close to straight. Foot types which are not aligned between the forefoot and rearfoot may have problems with minimal footwear. These foot types are often unstable due to imbalances and intrinsic weakness in the foot. As a result, there could be excessive internal rotation called overpronation. This places stress on the foot, ankles and legs. Because there is not a lot of support in minimal shoes, having good running mechanics is also helpful. But that doesn’t mean people who over-pronate or don’t run regularly can’t go minimal. If you don’t run regularly, beginning to run in a traditional shoe is important. After your body becomes used to running, the transition to a minimal shoe will be much easier. Try walking or doing light jogging in minimal shoes at first to help strengthen the muscles in the foot.
Pros
Like most things in running, there are pros and cons for going minimal. Some great things about going minimal is being more connected to the ground, improving your efficiency, form, and strengthening your overall body. This is not to say that someone can not improve their running form in a traditional shoe, however a minimal shoe can facilitate a more natural foot strike. A study by Daniel Lieberman (Harvard University) in 2010 showed that running barefoot/minimal puts less stress on the body, since you are more likely to land on your midfoot. After going minimal many people say that it is actually more comfortable than wearing a traditional soft, cushioned shoe. In the long run, minimal shoes may also help cut down on overuse injuries, because with a more efficient foot landing, there is less impact and rotation of the body. Minimal shoes are also significantly lighter than traditional running shoes, which cuts down on weight and improves flexibility.
Cons
On the other hand, there are some things to consider in wearing a minimal shoe: they have less support/cushion, it takes time to get adjusted to minimal shoes, and there is a higher risk of injury if not transitioned appropriately. For people who just begin wearing minimal shoes, there may be some soreness at first. It takes time to become fully adjusted to minimal shoes because you are engaging parts of your body that weren't being used before. Just as if you were strengthening your arms or legs at the gym, your feet need some time to become stronger also. Some common injuries for minimal runners range from shin splints to knee pain, to overuse stress fractures. Other injuries such as plantar fasciitis and achilles tendonitis are common, especially if you do not gradually transition into running minimal. Sore or even pulled calf muscles are also common because the transition to a midfoot strike engages more calf muscles. Overall, there are many different aspects that should be taken into account when choosing the appropriate shoe for you, whether it be minimal or traditional.
