Owners point the Adidas Ultraboost 5 at casual runners and walkers who won't rack up serious weekly mileage, and distance runners who prioritize long-run comfort over sprint responsiveness.
Owners point the Brooks Ghost 17 at daily trainers logging most of their weekly miles, and half-marathon runners wanting stable cushioning.
