New in Box. I also ordered a size too small for both kids. The adventure-ready Kensington Treklite is designed with the most ambitious explorer in mind. Updated this season with an upgraded Animal Free PU upper that’s water-resistant and easy to clean, as well as elastic side panels that stretch, and a removable foam insole for comfort. We went ahead and gave this boot a Treklite thermoplastic rubber outsole for strong, grippy traction to tackle all kinds of weather.
