If you are going to try out a bouldering wall for the first time, it is a good idea to read up about what you will need to take with you.
Pick the Right Chalk
Loose chalk is very messy but covers very well. Chalk balls are neat and can be used on very busy walls. Blocks of chalk are also available to buy as you can break off as much as you need. A very light coat on your palms is sufficient and the more you add the more grip you will lose.
Get the Shoe Fit Right
Climbing shoes are much tighter than normal shoes. They need to be tight enough so that there is no loose space at the front of your foot (toes). Most bouldering walls have a set of climbing shoes at the hire desk. You can then try them out before deciding to buy your own.
Wear Stretchy, Close-Fitting Clothing
Loose trousers can get caught on holds and restrict your movement without you even realising. Therefore stretchy joggers and/or leggings and a fitted t-shirt would be the best sort of clothes to wear. Jeans are not suitable as they restrict your hip movement on high steps.
Leave Jewellery and Watches at Home
This could cause serious injury and it is strongly advised to remove all items of jewellery including watches before taking part in any physical activity, including climbing.
