Why do I wear soccer uniform when I just practice football juggling or do independent training? This is because I want to practice wearing the same outfits as I would for soccer games. The same can be said for soccer boots.
Subtle differences in clothes or boots lead to differences in ball control. So I try to avoid wearing clothes that are too different from those for a soccer games. As I am in games, I wear compression shorts under my red soccer shorts.
But of course, I don’t always red clothes and black boots. As my team’s uniform are light blue and white, I wear compression shorts whose color is the same light blue or white.
And I don’ always wear compression shorts. I think compression is the best to wear under soccer shorts for mainly functional reasons. But In terms of comfort, boxer briefs or thongs are especially comfortable to wear during the hot seasons. So I’ve been experimenting with other options, especially in the summer.
