I like the R2’s for hurdles and shorter sprinting. I use the JA’s for the 200/400 because I feel like the plate is a little more flexible and a lighter overall shoe.
im going to purchase them soon, does anybody have a full review on them as most stores in the Toronto region are sold out in my size (9).
I wanna try them on, but the only way im getting them is through https://www.runningwarehouse.com/descpage-NIKSFLY.html so a little help will be greatly appreciated as I dont want to end up in a size too small or too big.
