There are 2 questions to ask about buying shoes.
- How important is having properly fitted shoes?
- How important is quality and value for money (value being price in relation to quality, not cheapest)
The thing is you can do better on both counts than Clarks. As other posters have said Clarks pedals with idea that unless your shoes are fitted by their shop assistants, your kids may wear poorly fitting shoes and have problems. Well, shoe fitting isn't rocket science and most people can learn to do it - how long do you think a Clarks shop assistant is trained in it for before being let loose? So, having shoes which fit well is important, but they don't have to be Clarks and you can learn to fit shoes yourself and may well find there are many styles which will fit as well or better...and be cheaper. It is the fit that counts, not whether they are described at being 10E rather than just 10. Because each shoes style comes up differently, receiving a measurement size and width can only be a starting point and any shoe needs individual fitting, based on it on the child's foot. The measuring gauge isn't some kind of magic. It may say one thing and an individual shoe may still be too wide or narrow or not the right shape. Look on the Start Rite website for a decent guide on how to fit shoes. Parents just need to have confidence that they are perfectly capable of doing it themselves. believe you can do it.
Then there is the quality and value. Clarks are pretty expensive for what they are. There are numerous other shoes available for less - look at M and S, or the better ranges in the supermarkets. You can get leather shoes for £20 not £38. If they fit your child (and you can only tell by fitting them and seeing, in the same way that you can only tell with Clarks by fitting too) then they will be as good as the Clarks one twice the price. It won't matter that say say 10 and not 10G.
Of course if you are a parent who needs to be able to say you bought width fitting shoes in order to hold your head up in the playground, this might be an issue.....but it really won't mean the shoes fit better.
And in terms of wanting the absolute top quality, Clarks are just not it. Other brands which may cost just three or four pounds more lies StartRite are usually better - leather linings for example, not some fabric thing which gives smelly feet. And there are also the European brands available in independent shoe shops. The staff there will fit you well and hopefully have a good range, but again, you could do the fitting yourself.
Online and outlet is a great source of shoes. You can often buy lots of pairs at pretty cheap prices and do the fitting in the comfort of your home and return the unwanted ones - often more choice than in a shop and much cheaper an no time pressure.
My top tip - learn how to fit shoes. Learn what to look for and how to feel them on the foot. Then you are freed to go wherever you like and to choose based on the quality and price you feel it is reasonable to pay.
