The other non-negotiable piece of kit that you need to start horse-riding is a pair of boots with a small heel. Wellies are no good, as the thick sole can get stuck in the stirrup. A boot with a smooth sole and a small heel – not stiletto – will help you keep your foot in the stirrup but won’t get stuck in the unfortunate case of a fall.
The last thing that’s pretty essential, as with most exercise, is a stretchy pair of trousers. The horse doesn’t do all of the work and you will need to move, plus have enough stretch in your clothes to be able to sit comfortably in the saddle. Jeans aren’t really suitable as they can rub your legs. Jeggings, leggings and tracksuit bottoms are all good.
