Our Verdict
adidas Questar 4
adidas Zenboost
The adidas Zenboost and Questar 4 are both good budget daily trainers, but they suit different runners. Get the Zenboost if you mainly run shorter distances and prefer more ground feel, a livelier ride, and a nimbler feel underfoot. Get the Questar 4 if cushioning is the priority and you want a more protective shoe that's better suited to extending your runs.
