When your moccasins soles look a little tired and in need of replacement (but tops are still in good condition), you can just chose to get a new pair of oil-tan leather soles and take them to a good shoemaker to be sewn on. These men's and women's oil-tan soles are made of thicker leather and will make your moccasins last you many more years. Please note: these replacement soles work with BASTIEN INDUSTIRES HIAWATHA earthing moccasins. These Chromexcel soles are tanned using time honored techniques and formulas that were developed nearly 100 years ago. Chromexcel is still produced using a bark retannage from a proprietary recipe, and then genuine hot stuffed with a secret blend of natural oils and greases. Modern Chromexcel carries on a long history of superior comfort and durability. They are available in ladies 5-10 and men's 7-15.
