Update #2: Isco today surprisingly switched to the almost four-years-old Nike Mercurial Vapor IX boots. He could debut the bold light blue, yellow and pink boots in Real Madrid's next league match against Betis.

Update: Isco today surprisingly laced up in blackout cleats as Real Madrid completed their fifth training session of the week, rounding off the preparations for their La Liga match against Osasuna on Saturday at the Santiago Bernabéu. However, Isco worked individually out on the pitch and is not included in the squad for Saturday's match.

Isco's new blackout cleats are the same as the regular version of the low-cut Nike Magista apart from the blackout look. Isco usually laces up in Nike's Mercurial Vapor 11 boots.

Isco's blackout cleats are the same as the regular version of the Puma evoSPEED SL-S 2016 boot from a tech point of view, while they boast a blackout look in order to hide that the Spain international is lacing up in Puma cleats.
Even though Isco today trained in Puma evoSPEED football boots, it is likely that he will switch back to the Nike Mercurial Vapor 11 for this weekend's match against Osasuna.
Do you think that Isco will join Puma? Let us know in the comments below.
