I'm happy with the Zante but have my eye on the 1500v4 as a lightweight trainer. I like the nice balance of cushion and responsiveness of the Zantes. I know the main difference is that Zante uses fresh foam and 1500v4 uses revlite and has some light support. Other than that, they both look similar in terms of sole thickness and drop with the 1500 being a tad lighter. I want to try going back to a support shoe but not sure if I loss some of the cushioning of the fresh foam that the Zante uses. Advice, opinions??
