4) Choosing the right size
What shoe size are you – ideally in UK sizing?
If you have running shoes and are happy with the size, then that is a good starting point. Read our sizing guide by manufacturer below to help if you are unsure about size or are changing brands.
Most running shoe brands make their shoes using USA shoe sizing. But be careful as there is no standard shoe form (or ‘last’ as it’s known in the industry), and the same size may be different from one brand to another. When each brand converts to UK sizes, they don’t necessarily convert the same – especially for Women’s sizes.
Tip: Go by what fits your foot rather than the shoe size on the box or shoe label.
Tip: Use the rule of thumb
With your foot in the shoe and with the shoes laced up, you should be able to get a thumbs width between the front of your big toe and the front of the shoe a little less is OK more is probably too big.
Tip: Other things to consider
If you are wearing through the toe of the shoe it might mean it is too short. If you are slipping in the heel it might mean your shoes are too long, or too wide.
Sizing guide by manufacturer:
(NB: this can change from model to model and season to season).
- Adidas – A little short and quite snug fitting so you might need a half size up.
- Asics – fairly true to size.
- Brooks – a little short but not enough to size up unless you are between sizes.
- Mizuno – Can fit a little longer/more generous. But you would only need to size down if between sizes.
- New Balance. These tend to fit a fraction short but generally stick to your size.
- On Running – These tend to fit a fraction short but generally stick to your size.
- Saucony – Generally true to size.
