Buying Guide

Picking the right shoe for you.

Consider coming into a store and doing a video gait analysis. Gait analysis monitors your body’s movement and your feet (sports biomechanics) whilst running. It’s commonly used to help athletes run more efficiently and to identify movement related problems for people with injuries who are seeking new running shoes.

Gait Analysis Daftfish

During gait analysis you will be asked to walk and run on our in-store treadmill whilst your movements are recorded using the latest Daftfish software. A slow-motion, detailed analysis will show and explain your biomechanics, specifically looking at pronation, the inward-turning movement that occurs when your foot touches the ground. During walking and running this acts as cushioning for the body.

Everyone’s gait is slightly different, but there are four main types of running styles and pronation:

  • Neutral Pronation
  • Over Pronation
  • Under Pronation, also known as Supination
  • Forefoot runners

It’s very important to know your running gait so that we can advise and fit the correct shoes according to your own individual requirements.

Can’t get into store? Try a wet foot test

Step onto a piece of heavy duty paper, card or even a bathroom tile and look at the footprint you leave behind. Seeing how much of the sole is visible in the footprint will help you determine the type of arch you have and which category of shoe you will need to buy.

Flat:  A flat footprint indicates that your aches are flat and therefore will need support. As your foot hits the ground your arch collapses in order to absorb the impact. If your arch collapses excessively, this is called overpronation and can lead to the ankle rolling excessively which over time causes some runners to develop pain. Overpronation in the arch can affect the whole body and cause discomfort in the heel, ankles, achilles tendons, shins, outside knee, outer hip, as well as the arches.

Normal: A normal footprint would indicate that the arches are high and therefore offer the neural support a runner needs. A neutral shoe makes up roughly 80% of available running shoes and have the same level of cushioning in the heel and the forefoot making it suitable for a large section of runners.

High:  A high arch would indicate supination, the opposite to overpronation. The runner’s arch does not collapse very much at all which can lead to less shock absorption. This will concentrate the force of the impact toward the outside area of the forefoot leading to some runners that supinate experiencing foot pain or even stress fractures as a result. Runners that supinate may want to consider a highly cushioned neutral running shoe. The greater level of cushioning in these shoes can help absorb more of the shock from impact.

Size is important

When choosing a running shoe always consider the sizing. As you run, the blood goes into the foot causing it to naturally swell. If there isn’t enough room for the foot to breathe then it will cause friction against the inside of the shoe and eventually lead to blisters. We advise a thumb width at the front of the shoe, from the tip of your big toe to the end. If you are running up to a half marathon we would advise going up a half a size to your normal shoe size. If you are running further than a half marathon or training for a marathon then it would be advisable to go up a whole size. Having plenty of room will also make the shoe feel much more comfortable.
 

Seasoned runner – if it’s not broken why change?

If you have had a good experience with your old shoes and have stayed injury free then you might, understandably, be reluctant to change brand or model. Be sure to look at the latest version of your current shoe as most popular styles tend to be slightly tweaked rather than completely redesigned when updated. The fit and feel is always very similar if not exactly the same. It’s evolution rather than revolution!

Wear and Tear 

Why do you need to replace your running shoes if they still look unworn? The simple fact is that a running shoe will act as a shock absorber for your muscles and joints through its cushioning. This cushioning will usually last for approximately 500 miles. After this, it compresses and then more shock is being put through the body and this can lead to muscle fatigue and injuries. The most obvious sign that a shoe has reached the end of its life is wear and tear. Flatter or smoother tread is one of the clearest indicators that it might be time for a replacement. The wear on your shoes can give an indication of your natural gait. If the upper has split near the toe box you might want to consider going up a half a size or in some cases, change the width of your shoes. For example, a standard width in a men’s shoe is a D width but the 2E width will be wider around the bridge and forefoot allowing the foot more room and therefore not creating friction that leads to the upper splitting and not supporting the foot correctly.
 

Comfort is KEY!

If your new shoes aren’t comfortable then you won’t enjoy running in them. You have a unique shaped foot and all brands are different in the design, shape and fit.  It is advisable to pop to your local running specialist and try on a few different brands, on the treadmill if possible, to get a feel for the shoes. If you can’t get to a local store, wear them around the house for around 30 minutes to give you an idea of the fit and feel before running outdoors.
