冇錯又講呢個款，萬眾待望flyknit加襪筒設置改革號，然而細路如我對Air Presto嘅碼數唔係用半號上數字區分而係用上衫的S,M,L的分碼感真係唔清楚。今回得到同樣為Nike球鞋設計師，Tinker Hatfield的弟弟Tobie Hatfield親自解畫。

原來 Tobie在設計出Air Presto初型試找來測試者體驗新鞋款，誰知他卻在沒有告知該君的情況給了9號鞋予原來11號腳的測試者，可是 tester試完新鞋給予評價時，卻對air presto讚口不絕，並且不相信該鞋的size細了兩個碼。由是引發 Tobie奇想，認為鞋碼未必雖要那麼accurate，只需有一個範圍，就如衣飾的碼數以S、M、L等劃分已經足夠，無須分得那樣仔細。最後Nike Air Presto就以S、M、L等方法劃分咯！ 

“ This sparked an insight…I realized that maybe we could consider a “range” of size instead of a more exact “half-size” that was the current norm. T-shirts and other apparel are made with size ranges, so why couldn’t we do that with this specific shoe?”
