Hi I just wanted to say a big thankyou to you at walktall I ordered a pair of columbia buggaboots size 13 they are the best foot wear I have ever bought. I recently went to the sahara desert and walked for 70 Kilometers in 4 daysfor charity. I crossed streams shallow rivers miles of sand dunes and rocky terrain. They cost 110.00 but wow what a boot really comfortable and light weight fully waterproof not one bit of sand got in. never rubbed and did NOT need breaking in. I will highly recommend these boots for all types of trekking.If you want to sponsor me you still may. http www.justgiving.commalcolmallcockMalcolm Allcock Dorset
