So there it is, the thread you been waiting for. Why I want a drop is because I had experience with the Brooks Ghost 12 and although I did not like the fact that they are heavier, I think the 12mm drop is amazing because it encourages you to move forward and seems to be more energizing. If you don't like a high drop please leave this thread to others. Here is the result of my research so far (took me weeks to compile this):
Brooks T7 - 6.0 oz. 11.9mm drop
Asics Tartherzeal 6 - 5.6 oz 10mm drop
Brooks Hyperion - 6.4 oz 10mm drop
Nike Vaporfly 4% - 6.9 oz 9mm drop
New Balance 1400v6 - 7.10 oz 10mm drop
New Balance RC1600v2 - 5.4oz 8.3m drop
Nike Mayflys - 4.7oz 9mm drop
Adidas Adizero Feather 4 - 6.4 oz 9mm drop
So as you can see, extremely lightweight shoes, all have a heel height 8 to 12mm higher than the forefoot height, and the question that can't be easily answered is are they comfy. Now of course I would buy the Vaporfly but three problems: they are difficult to find, the price is a little high and the flexibility is not good. But I still consider them.
So what is the best shoes, 7.5 oz or lower, 8mm+ drop and most comfortable? This thread is now yours to participate and add more suggestions.
