Today, I'd like to share the features of the ADIDAS X SPEEDPORTAL.1 series and compare it to the previous generation X SPEEDFLOW.1. I hope this will enrich your knowledge. 
Shoe shape design
Firstly, the SPEEDPORTAL.1 is longer than the previous generation. The left lace is positioned higher, increasing the area where the left shoe contacts the ball, which significantly enhances the feel of ball control and foot contact.
In addition, more carbon fiber elements are added to the boot. The two lightweight carbon fiber plates at the heel position more effectively fix the heel position.
stud design
Unlike previous stud designs, the SPEEDPORTAL.1's studs are triangular in shape, making it easier to turn when the sole rubs against the grass, providing more explosive power while also ensuring grip.
In-shoe design
The heel cushion is enlarged to provide users with more comfort and reduce heel fatigue after long-term wear.
Upper material
Compared to the previous generation, the SPEEDPORTAL.1 has a more elastic and resilient upper with higher rebound and more direct force transmission. Slightly raised triangular beads on the inside of the upper enhance friction when the upper contacts the ball.
Technology support (carbon fiber technology CARBITEX)
As mentioned above, in addition to the two carbon fiber plates at the left heel, the sole also incorporates a larger area and longer carbon fiber material to provide users with lighter weight, higher resilience and more explosive power.
Please note that the tongue elastic position of SPEEDPORTAL and SPEEDFLOW is different, so the wearing feel will be different.
Anyone interested, please try it at the Kwun Tong or Tuen Mun stores.
