Compared to Converse All Star

Converse All Stars feel similar in length despite being 5mm longer due to their narrow toe box. Prototype-01 offers a wider, roomier toe area, a thicker, more supportive insole for a snugger feel.

 

Compared to Vans Old Skool

Prototype-01 shares similar length and width with Vans Old Skool, but provides enhanced volume around the toe (especially inner ball) for a more comfortable fit, particularly for higher insteps.

 

Compared to Nike Air Force 1 & Adidas Stan Smith

Sizing for Nike Air Force 1 and Adidas Stan Smith is comparable to Prototype-01. However, if you wear them "just-fit," our shoe might feel slightly shorter or tighter (Stan Smith is longer/narrower,  AF1 is longer/wider).

 

Compared to Adidas Samba

Adidas Samba is shorter and narrower. Prototype-01 is a half to a full size larger than Samba.
