These wellies are made from a natual flexible and lightweight rubber so they can be rolled up and down for easy carrying or packing. You know what that means - puddle jumping or running through the mud never has to be off the cards if you keep these in a bag or the boot! Aside from being able to play in the rain what theyll love most is the hand-drawn print that adorns the wellies and the unique-to-Joules measuring tape to the back which will allow them to measure the depth of puddles or snow. When it comes to grip the water dispersing outsole pushes water outwards giving the foot better contact with the ground. To ensure they stay in tip-top condition weve given them an easy wipe-clean construction and made the insoles removable so they can be washed or replaced when needed. There really are so many more features to explore (including a reflective back strip for safety when the grey clouds make it a little darker!) Psst... when storing the boots ensure you unroll them so they stand upright until their next use.
