There's a difference between using some Liquid Nails to put a sole back on and getting your shoes professionally resoled.

Cemented shoes and boots, being those that are fused and/or glued to the upper in most cases cannot be resoled. Once the soles peels away, it's not uncommon for the midsole to as well which pretty much cements (haha) the fate of the shoe.

Cemented soles are virtually impossible to effectively resole. A lot of cobblers will turn away shoes that are cemented. Welted boots are always going to be a better investment, Goodyear or otherwise.
