We should protect ourselves from the impact of running with appropriate cushioning.

The argument

A practical argument against barefoot running is that running generates substantial repetitive impact forces, and that cushioned footwear exists precisely to absorb and reduce those forces, protecting the body from harm. Each stride sends a shock through the foot, ankle, knee, hip and spine equivalent to several times the runner's body weight, repeated thousands of times over the course of a run and millions of times over months of training. Modern running shoes are engineered with cushioning materials specifically to dampen this impact, spreading and softening the forces that would otherwise be transmitted directly into the joints and bones. To run without that cushioning is to expose the body to the full, unmitigated shock of every footfall. Proponents argue this matters especially on the hard, unforgiving surfaces most people actually run on. Concrete pavements, asphalt roads and treadmills are far harder than the natural ground humans evolved to move across, and the repeated impact of running on them is a recognised contributor to overuse injuries such as stress fractures, shin splints and joint problems. Cushioned shoes act as a buffer between the foot and these punishing surfaces, reducing the peak forces that drive such injuries. Removing that protection, the argument runs, simply increases the load the body must absorb on every stride. From this standpoint, the sensible course is to use the protective technology available rather than discard it. If repetitive impact is a genuine cause of running injury, then cushioning that reduces that impact is a benefit, not a hindrance, particularly for the high mileage and hard surfaces of modern running. Because we should protect ourselves from the impact of running with appropriate cushioning, this argument holds, barefoot running is not better for you.

Premises

Counter-arguments

Barefoot and minimalist advocates reply that cushioning does not simply subtract force — it changes running form. Thick heel cushioning encourages a rear-foot strike that produces a sharp early impact-force peak, whereas barefoot and forefoot runners tend to land more softly and flatten that peak. So more cushioning can shift how and where impact is applied rather than straightforwardly reducing injurious load. They add that the evidence cushioned shoes actually prevent injury is mixed: trials comparing shod and minimalist runners have not shown a clear injury advantage for cushioning, and some research links the muted sensory feedback of thick soles to worse gait control. The protective-technology framing therefore assumes what it needs to prove.

Rejecting the premises

[Rejecting P2] Cushioning can shift running form toward a heel strike that raises the impact peak, so shoes do not simply "reduce" force — they change how it is applied. [Rejecting P3] The claim that removing cushioning increases injury is empirically contested; trials comparing shod and minimalist runners have not shown a clear injury advantage for cushioning.
