Kofuzi calls the Aero Blaze 4 a nostalgic, road-feel daily trainer that's essentially identical to the Aero Blaze 3, but thinks it's priced a little higher than it's worth.
Best for: Runners who miss older-style, ground-feel daily trainers rather than max-cushion shoes.
Kofuzi notes: True to size for most runners; toe box volume is average to slightly shallow in height.
