The first impression is a huge difference from the T9. The T9 is softer and more flexible, while the T10 is much more firm. While the T10 isn't made of kangaroo leather or denim leather, but uses the fly touch plus, it feels like an upgraded or evolved version of the Kanga Lite on the CTR 360. (Personally, I prefer a slightly stiffer upper, as it feels a bit more firm.)
In terms of shoe shape, I think it will be a little narrower than T9, probably because its upper will not stretch as much, plus visually the T10 shoe shape will be a little narrower than T9.
As for the T9 and T10, I personally think that the biggest difference, apart from the left upper, and the most surprising thing for me, is the wrapping feeling of the middle and rear section of the T10. Because I didn’t like Tiempo before because the wrapping of the middle and rear section was not enough for me. Although I used flyknit before, it was only used on a small part of the tongue. But this time, whether it is the area of flyknit used or the elasticity and strength, the wrapping of the middle and rear section of the T10 is much better.
The T9 series uses a large amount of engineered mesh on the heel, which is used in all generations. Only a small part of the heel is used. The coating is added from the outer Nike logo to the inner Nike logo and the middle and rear part of the sole. On the one hand, it may strengthen the support of lateral movement on the outside, and on the other hand, it may increase durability. Because some people are confused or worried about the durability of the T9's heel, there will be some changes this time.
As for the studs, there are no changes. The only difference is that the support beams in the channel have a new design.
Overall, I feel that the changes and sincerity of T10 are sufficient and satisfactory, but my biggest concern is the durability of the thin tag on the outside of the shoe.
