Zoom Freak 4

Better aesthetics compared to previous three generations, looks cool overall

Comfortable fit and significantly improved wearing experience compared to earlier models

Design reuses many elements from previous generations with limited innovation

Cushioning system identical to last year with no new technology upgrades

After a few days of break-in, traction performs well and provides solid grip on clean courts

Very smooth heel-to-toe transition with curved forefoot design that rocks forward easily and good forefoot flex, making it comfortable to wear with no foot pain

Traction is not ideal when first worn and requires several days of break-in to reach optimal performance

Thin and soft rubber outsole, widely spaced tread grooves that don't pick up dust, not suitable for outdoor use, and limited midfoot torsion support

Improved stability - The lightweight foam on the sides and reinforced lace lines provide better lateral support compared to the Zoom Freak 3

Excellent responsiveness - Dual independent Zoom air units deliver strong bounce with a 42.5cm jump height, second only to the Puma TRC Blaze Court this year

Lack of midfoot shank - Removal of the stiff midsole shank from the Zoom Freak 3 causes the foam to bottom out quicker, reducing support and durability

Reduced structural support - While the heel's gritting pattern adds comfort, the overall flexible design may compromise stability during extended gameplay
