These wellies require minimal 'setup'. Upon first wear, adjust the side gusset using the buckle fastening to achieve a snug yet comfortable fit around your calf. Ensure there's enough room to move without feeling loose or restrictive. These adult wellies are designed for women and are available in various UK sizes (e.g., UK 5 for this specific variant). To care for your Joules Houghton Wellies and ensure their longevity, wipe them clean with a damp cloth after each use, especially if they are muddy. Allow them to air dry naturally away from direct heat sources or sunlight, which can degrade the rubber over time. The removable insoles can be taken out and aired separately to maintain freshness. Store them upright in a cool, dry place. Regularly check the rubber for any signs of wear or cracking, though they are covered by a One Year Welly Guarantee.
