Walking shoes can be expensive, and there are certainly a lot available. If you're feeling bemused, try our buyers guide to make sure you don't pick up a pair of winkle-pickers.

1. The fit of your shoe is important - make sure it's flexible, more flexible than a running shoe. Make sure your toes have room to move also.

2. Get a breathable shoe - it's better for your foot. Also, pick a mesh-style fabric over leather footwear.

3. The single most important thing about a shoe is comfort. If it doesn't feel right at first, don't buy it. Don't wait to "break them in" otherwise you'll develop foot problems fast.

4. Your feet can swell up to one whole size during the day, so it makes sense to get measured at the end of the day - when your feet are at their largest.

5. If you are unsure what socks to wear, either wear your normal ones or ask at the shop for special walking socks. These are generally synthetic meaning they will compress less and dry out more quickly

6. Allow about an inch and a half of space from your longest toe to the end of the shoe. This will mean you'll still have space when your feet swell up. Make sure all your toes have room to move.

7. Make sure the shoe is as wide as possible without slipping on your foot. Too narrow will cause problems but slipping will mean blisters or worse.

8. Make sure to try on both shoes before purchasing - your feet may be of a different size. Although in normal shoes this isn't really a problem, any imperfections will be magnified when walking long distances. Get a bigger size if necessary.

9. It's time to replace your current walking shoes when they cannot offer the proper support for your feet. They'll feel worn down and flat. For a good comparison, go to the shop and try a new pair next to your old pair - they'll probably offer much better support.

10. Walking shoes are about function - not fashion. Don't be taken in by sales spiel when the number one factor is supporting your foot and avoiding injury.
