>>635851I've been looking into durable lightweight combat boots and the Belleville TR900 Jungle Runners seem to be functionally the same as Nike SFBs but with much better build quality as far as the soles go. The midsoles on Nike SFBs sometimes peel off from the upper after a short period of normal usage, but the Jungle Runners are stitched all the way around.
I've come to the conclusion that Nike SFBs are about as weak as any Nike running shoe. They may be comfy enough for you to go and buy your $4 latte every morning, but if you use them on the trail for any reasonable length of time they will disintegrate.
Also, sweatshops.
