Waterproofing treatment should suit the boot's materials and construction. It cannot repair every leak or turn any boot into winter mountaineering footwear.
Clean before treating
Remove dirt using the manufacturer's recommended method. Check seams, soles and obvious damage. A damaged boot may need repair or replacement rather than another surface treatment.
Use the correct product
Leather, fabric and membrane-lined footwear can have different care requirements. Follow application and drying instructions. Avoid heat or household oils unless the manufacturer explicitly recommends them.
Test before the trip
Check the result on an ordinary walk and plan spare socks. Read the boot-cleaning guide. For an Atlas winter route, confirm equipment compatibility separately; improved water resistance does not establish the warmth, stiffness or technical suitability the itinerary may require.
