Among the three kinds of football shoes listed in the question, Mizuno's Morelia series should be the best in evaluation and workmanship, and Nissan Sakya has a good reputation. As for Legend 5, objectively speaking, it is a great failure of the Legend series. Although the foot feels excellent, it is very inappropriate to choose the inside of the foot that frequently touches the ball as the leather unsealing place, and it is very easy to open the thread during use. At the same time, it is as easy to open glue as Sakyamuni.
Mizuno morella is excellent in workmanship, lightweight design, shoe type and quality. Perhaps this kind of shoes are not very popular in professional football, but they are very popular in amateur football, especially in Asia and China.
There are also several ASICS real leather shoes, which are also very good.
As mentioned earlier, Nissan is actually made in Japan. As the largest producer of traditional leather soccer shoes in the world, Japan not only has its own brands such as Mizuno and ASICS, but also OEM other brands such as Adidas and Puma. It can be said that "Made in Japan" is the quality assurance of traditional leather football shoes.
