I tried this once, and failed. By the time a major seam of a well-made backpack fails, they are all, about to fail. My backpack was 5Y old and was in the "wearout" phase of life, where everything fails at once. Replacing an important zipper completely (seams had failed, not zipper itself) only gave my pack another 6 months of life. Yes, a shoe repair shop is the right place to go, but $90/yr is an expensive backpack indeed! I currently have a Yellow Columbia half-track and the quality is unreal, I've used it every day for 6Y, with laptop+clothes+gear, no damage yet!
