Carbon-plated 'super shoes' deliver a real running-economy benefit, but the biomechanical changes behind it may carry a bone-stress-injury cost for some runners
Interpretation
A 14-trial meta-analysis and a dedicated recreational-pace RCT both confirm the metabolic/economy benefit of plated shoes is real and extends beyond elite athletes. But a 2026 biomechanics study in elite distance runners found decreased cadence, more overstriding, and greater arch collapse in the same shoe category — plausible mechanisms for bone stress injury that the economy literature doesn't address at all.
Practical implication
Don't treat 'faster' and 'safer' as the same question for super shoes. Economy gains are well-supported; injury risk is an emerging, mechanism-level concern that should inform gradual adoption (not racing exclusively in a new shoe without build-up), not a reason to dismiss the shoes outright.

Found decreased cadence, increased overstriding, and greater arch collapse in advanced-footwear-technology shoes versus traditional shoes — plausible biomechanical mechanisms linking super shoes to bone stress injury risk, though this is an observational/mechanistic link, not a causal injury-incidence trial.
