As others mentioned. SIZE UP! All my other Nike footwear are size 11 and fit great. I ordered these in 11 and they are AT LEAST 1/2 size too small. Very tight! Good sole and outsole seems durable. Bounties will tell.

FIELD-READY STABILITY AND TRACTION.
Built for special operators and elite outdoor athletes, the Nike React SFB Carbon packs the durability, support and traction of a tactical boot into a rugged shoe. The full-length carbon plate helps optimise your stride, while responsive Nike React cushioning provides comfort for the long haul. The aggressive tread gives you excellent traction wherever your mission or adventure takes you.
Stable structure
Nike Flyplate technology made from stiff carbon fibre optimises your stride while providing support to help minimise fatigue, ease pressure on your Achilles and reduce slipping inside the shoe. The plate acts as an internal rock shield while the outsole helps against punctures.
Comfort with energy return
Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. The more energy you put into your step, the more you get in return.
Serious traction
A combination of hard and sticky rubbers makes up the aggressive sole pattern, giving you durability in heavy strike zones and exceptional traction in natural and urban environments. The rubber teeth in the arch add grip when you're climbing ropes or covering rugged terrain.
Reinforced support
Strong fabric wraps the midsole for containment and stability. Solid rubber reinforces the toe.
More benefits
- Mesh helps keep your feet cool and dry.
- Overlays in high-abrasion areas add durability.
- Heavy-duty laces.
- The laces stow away to help reduce distractions.

I thought I ordered the wrong size or was sent the wrong size. Nope, it was the size I ordered. I can’t wear these things they are at least 1/2 to full size to small. Really wish I didn’t waste my money on these. BEWARE BEFORE BUYING SIZE UP!!!! Nike needs to do better!
Design flaw with glue?

Coming apart where sole meets upper and only with gentle wear, not hiking, running etc.
