You Can Better Select A Shoe Based On Fit And Durability
Runners understandably place a high premimum on the durability of their running shoes. With shoes costing upward of $85, runners expect their shoes not only to fit and perform well, they want them to last. But for how long? Sorry. There’s no reliable way of telling exactly how many miles you’ll get out of a pair of running shoes – there are way too many variables – but by understanding the materials shoe companies are using to build shoes, you can better select a shoe based on fit and durability.
Running shoes are made up of three basic components: the outsole, the midsole and upper. Each of these components can be made of materials that vary greatly in weight and density. As these components are put together to construct a running shoe, there’s a wide range of durability factors.
Basically, if the materials are high in density and firm, the shoes provide greater support and will last longer. Durability is largely determined by the density and firmness of the midsole foam, hardness of the outsole rubber and strength of upper materials.
Outsole rubber can vary by type of rubber used and the brand. There are two main types of outsole rubber used in running shoes: carbon and blown (or expanded, the terms are synonymous). Blown rubber is so-called because air is injected into the rubber compound for a softer, lighter outsole. Blown rubber is most commonly used in the forefoot because it’s more flexible, cushier and softer–right where you need it.
But the downside is blown rubber is not nearly as durable as carbon rubber which is heavier and harder. Because blown rubber lacks durability, there are few running shoes made today with blown rubber in the forefoot and rearfoot of the outsole. Most commonly, blown rubber is used in the forefoot and carbon is used in the high wear areas of the rearfoot.
Midsoles are the key to any shoe – and especially the durability. (If the midsole is worn out, it doesn’t matter if you still have plenty of outsole life. The shoe is shot and a new one should be bought.)
There are two main midsole foams: ethylene vinyl acetate (EVA) and polyurethane (PU). EVA is a sponge-like foam that is soft and relatively light. But it lacks stability and durability. Polyurethane is heavier and denser (and more durable) and when it’s molded, it creates a firm outer shell creating good stability in the midsole. But there’s a trend away from full polyurethane midsoles as most runners prefer the lighter, cushier EVA.
Shoe geeks frequently use the term “compression set” when discussing midsoles. It refers to the ability of a foam to return to its original shape after being compressed during running. The higher the compression set, the more durable a shoe is. PU has a very high compression set, while typical EVA is much lower.
But EVA is generally smoother and better at higher running speeds than PU. However, PU is more stable and better for the bigger, heavier runner who greatly compresses his shoes because of his size.
Upper materials also vary greatly from light, open mesh to heavy, waterproof materials. The more efficient your footstrikes, the faster you are, the less support you generally need from the upper materials. If your feet overpronate, a heavier weight upper can provide greater support – and more durability.
With all the combinations of materials and new looks for running shoes, it is important to know the different types of materials used in construction and their benefits so you can pick out the best shoe for you – and the most durable.
Bottom line: The most durable running shoes have polyurethane midsoles, supportive uppers and carbon rubber outsoles. But polyurethane is being used less and less so at the very least, look for a shoe with a carbon rubber outsole and a multi-density midsole.

How to Choose the Right Retro Running Shoe For Your Foot Type
Running is a terrific way to stay fit and is usually a lot of fun, as well. It is crucial to ensure you have the correct gear prior to starting and probably the most vital investments is a good pair of retro running shoes. They might improve your running stride and prevent accidental injuries. There are 1000s of different running sneakers to choose from and the majority of the big sports manufacturers invest money into the science and technology of athletic shoes.
Running Shoe Components
A retro running shoe consists an outsole, a midsole, an top, a heel counter and a post or footbridge. After that, running sneakers vary substantially in design and color. A running shoe should be adaptable and tough, control motion and absorb shock. I suggest you buy your sneakers from a specialist running shop, or at least a sports store, so you can get helpful advice from the sales employees. Try on shoes in the afternoon, when your feet are a bit larger.
Every individual has slightly distinct feet, so a great shoe for someone else may not necessarily be the best one for you. The shape of your foot, weight, any foot problems, your jogging style and running surfaces (tarmac, mud, treadmill etc) and other sorts of components can impact which running shoe is going to suit you and your life style the best.
Kinds of Running Shoes
You can divide your feet into one of 3 standard types regular, flat or high arched. Have a look at your wet footprint on the bathmat when you are getting out of the bath. If you see a complete imprint, this implies you are flat footed. If there is an arch cutaway, your foot is normal. If there is a very thin band or no band in between the front and back of the foot, you could have high arches. Foot type impacts which kind of running shoes will be better for you. The normal foot tends to be the most biomechanically efficient and you will need shoes with moderate motion control. If you have high arches, stay away from stability or movement control shoes, as these will limit foot range of motion. If your feet are flat, high stability or motion control shoes with firm midsoles will lessen the amount your foot naturally rolls in and be more comfortable and better for you. Stay away from highly curved or padded shoes if your feet are flat, because they will restrict balance.
When trying on retro running shoes, make sure they feel good as soon as you wear them. The typical pair of running shoes will be able to run one thousand km so comfort is a must!
