Adidas SP4 Big Cicada Wing Generation 4 JI1212 Size 42

According to feedback from most athletes, adidas shoes tend to run 0.5 to 1 size smaller compared to regular sports shoes or brands such as domestic spike shoes, Puma, Asics, and Mizuno.

For specific size recommendations, please contact online customer service.

It is advised to select a shoe model that matches your foot shape to ensure the front spikes can function effectively.

Shoes that are too wide may result in insufficient upper foot wrapping.

Shoes that are too narrow may create extra space at the front toes, causing a mismatch between the foot’s pressure points and spike positions, which can negatively affect traction performance.
