KD 9

Upgraded Flyknit material is softer, thinner, and more breathable than the original

New lacing system design is beefier and provides better lockdown around the foot

Visual design is too similar to original KD 9, lacks innovation

Casual aesthetic is not appealing, better worn on court than off

Excellent cushioning comfort with Lunarlon foam and Zoom Air unit combination, providing great impact protection and soft feel

Innovative lacing system with unique rear cable wrap design effectively locks down the ankle for enhanced stability

Average traction with rubber compound and pattern design that accumulates dust on slightly dirty courts and is hard to clean

Insufficient support despite premium materials; softer padding design compromises overall lateral support, especially with the softer cushioning

Outstanding cushioning system with full-length articulated Zoom Air, lower profile design provides better court feel while maintaining excellent impact protection and responsiveness

Premium upper materials, full Flyknit forefoot without glue or fusion allows one-to-one fit with zero restriction, and requires virtually no break-in period

Sizing runs large, true size feels slightly long with half-size down being more comfortable though requiring break-in period

Heel collar design inconvenient, non-stretching collar makes putting on and taking off the shoe somewhat difficult
