I don't buy expensive shoes, so it seems obvious to me that it's cheaper to replace than repair, so I do that. But I do have one expensive ($150 on sale, $300 retail) pair of winter bike boots, and the soles gradually detached from the uppers, letting water seep in. I took them to my local shoe repair place and they made them good as new for $25. Total bargain. So, it's worth a shot.
