You can! You just need to beat the Goblin Army, free the Goblin Tinkerer and buy the Tinkerer's Workshop and Rocket Boots from him, then you can combine them with your Hermes Boots. While I didn't mention the Tinkerer by name in the walkthrough, he's extremely helpful, as he allows for Reforging and stuff. I wouldn't have had those +def bonuses on my accessories without him.
