There's no single 'best shoe' - everyone has different needs. All sorts of things - your biomechanics, your weight, the surfaces you run on, and obviously, the shape of your feet - mean that one person's ideal shoe can be terrible for another person.

The Normal Foot
Normal feet have a normal-sized arch and will leave a wet footprint that has a flare, but shows the forefoot and heel connected by a broad band. A normal foot lands on the outside of the heel and rolls inwards slightly to absorb shock. It's the foot of a runner who is biomechanically efficient and therefore doesn't need a motion control shoe.
Best shoes: Stability shoes with moderate control features.

The Flat Foot
This has a low arch and leaves a print which looks like the whole sole of the foot. It usually indicates an overpronated foot - one that strikes on the outside of the heel and rolls inwards (pronates) excessively. Over time, this can cause many different types of overuse injuries.
Best shoes: Motion control shoes, or high stability shoes with firm midsoles and control features that reduce the degree of pronation. Stay away from highly cushioned, highly curved shoes, which lack stability features.

The High-Arched Foot This leaves a print showing a very narrow band or no band at all between the forefoot and the heel. A curved, highly arched foot is generally supinated or underpronated. Because it doesn't pronate enough, it's not usually an effective shock absorber.
Best shoes: Cushioned (or 'neutral') shoes with plenty of flexibility to encourage foot motion. Stay away from motion control or stability shoes, which reduce foot mobility.

Choosing the next pair of shoes, we are followed by aesthetic preferences paying attention first of all on color and style and hoping that for the sake of such beauty it is possible to endure any discomforts.

And then suffering from corns, abrasions and pain in the joints, reprobate themselves in unwarranted sacrifice and put on frayed and comfortable shoes removing newly purchased shoes to the best times.

To avoid such disappointments it is necessary to remember that the main qualities of footwear is a comfort and practicality. Before trying on the liked pair you need to carefully examine every shoe from toe to back.

The leather in these places should be flexible and elastic, especially in the shoe back.

You can slightly push on toe and back and look how shoes will behave: the dents disappear without a trace on the high-quality and right processed leather.

Then you should thoroughly probe an idem areas. As a rule in high-quality footwear an edge of under the toe and back through thick of top is not feel. Inside the edging of a back should not be sharp and bent inside.

Now check the sole on a curve to determine whether under the surface a metal instep-raiser. Bad shoes can be cracked during the wearing. The inside part of shoe back should not be too stiff and the form of a track should correspond with a foot.

Please draw attention on a lining. If it is dark colour then it is necessary to be afraid of colouring of foots.

And finally - dress in! It is very important to pick up footwear on size, therefore it is very important to try on both shoes. Extend on weight from heel on toe to check up whether fingers are free.

Assurances of sellers that the footwear is worn in can quite appear the truth but you should wear in, so...

But no panic to the other extreme measure - too free footwear will be looked on a leg ugly! Besides, your foots having felt unexpected freedom will refuse to get into narrower shoes in future.

After buying a shoes wear them at home. So you can once again be certain of a right choice.

If the defect will suddenly be found out in a new pair you can exchange them in a shop.

Term shoe guarantee is 30 days on default, but some manufacturers sometimes raise it. Ask sellers for guarantees terms.
