Extremely durable... zero wear and tear!!! Thankfully, there are these spare parts so we don't have to make extra purchases for 2 pairs of shoes!!! Don't worry, they are so well-made by the company that no stud will be lost on the field... but be careful with screwing and unscrewing, it doesn't require excessive force, neither too tight nor too loose, so that the studs don't break and render the entire football useless! Pay attention, it is only suitable for the new models (half and half... whether they are economical or professional) of adidas... it doesn't fit at all with Nike or Puma or any other brand because it has a greater thickness and socket for the corresponding stud... it tightens, it doesn't even fasten!!!
