We have a range of walking boots that includes single and dual density soles with breathable waterproof membranes to keep feet cool and dry, making them suitable for different types of terrain.
Single density soles comprise a single layer rubber sole with impact absorbent insoles. These boots would be suitable for walking on even terrain such as footpaths and low land walks (think South Downs Way, Surrey Hills).
Dual density soles provide protection against higher impact and are more suitable for walking in a rockier, less even terrain. These are ideal for hill walking and trekking e.g. through the Yorkshire Dales, Lake District or the Welsh countryside.
