differences between a few nike running shoes

I found myself looking for running shoes and found myself a little overwhelmed by all of the choices out there. My goal was to find a semi-minimalist shoe – basically a cross between a flat, minimal shoe with no heel-toe drop (difference in height between the heel and the toe) and a traditional running shoe that typically has a bunch of heel cushioning. I realize that the minimal shoes are already a cross between shoes and barefoot running, but my legs and calves aren’t quite ready for that yet.
I focused solely on Nike shoes. Nike’s website, while pretty, sucks for obtaining any technical information. Luckily, Running Warehouse has a lot of good information. They have a neat shoe fit predictor (“shoefitr”) and good information about the amount of support running shoes provide as well as measurements of heel to toe drop.
Nike Free series:
I like the Nike Free series because they allow your foot to flex naturally, which allows you to build up strength in your foot muscles when training. There are a ton of different variations out there and it’s hard to tell what the differences are.
-
Nike Free 3.0 – most barefoot-like with a super flexy sole
-
Nike Free Run + (or variant, however model name must include “run”) – formerly known as the Nike Free 5.0 -
super flexy sole like the 3.0 but with about 4mm more cushioning throughout

Anything with “TR” in the model name is for cross training. This isn’t always obvious. There’s also a Nike Free Walk walking shoe. The Nike Free Xilla is a cross training shoe. I don’t know what the Nike Free Waffle AC is exactly other than it uses the Nike Free sole with an old school upper. I think it’d function as more of a cross training shoe.
Nike Lunar series:
I did a lot of research on the Nike Lunar series (I purposely focused mostly on these to make my decision easier) and here’s what I’ve found for heel-toe drop. Once again, Running Warehouse was a great resource:
-
Nike Lunar Racer – 27mm heel height/21mm toe height: 6mm heel-toe drop
-
Nike Lunar Spider – 22mm/16mm: 6mm
-
Nike Free Run (or Nike Free Run+) – 25mm/18mm: 7mm
-
Nike Free 3.0 – 21mm/14mm: 7mm
-
Nike Lunar Fly (or Nike Lunarfly) – 29mm/19mm: 10mm

-
Nike Lunar Swift – 26mm/16mm: 10mm – has more pronation support (which I did not want)
-
Nike Lunar Elite – 31mm/20mm: 11mm

-
NB 101 – 26mm/16mm: 10mm
-
NB minimus 10 – 19mm/15mm: 4mm
