I spoke too soon. I found this in a paper on shoe protection and running performance:
"It is commonly believed that wearing lighter shoes with fewer protective features can
save energy. While oxygen uptake my be reduced by 1% or so for every 100 grammes of shoe
weight saved, the runner’s kinematic adaptations to reduced cushioning has been found to
produce a similar increase in oxygen consumption. Therefore, most runners have little to gain by
selecting shoes that lack risk-reducing features."
So minimal cushioning is bad for you too: you don't really gain anything energetically overall, and the risk of injury is greater with minimal cushioning.
