It depends. I do replace insoles sometimes. It seems like many of the athletic shoes tend to have the fabric wear through or the tread wear off in about 1-2 years depending on the design and materials. Dress shoes tend to last a year or two longer for me, until the leather gets too bent up looking. Some of those designs have sewn and glued insoles which are not easy to replace.
