Here's what I found a while back when seeking info about tumor necrosis. 1) Necrosis in the tumor means that the cancer cells in that area are dead. The pathologic finding of necrosis suggests a fast-growing cancer. This often happens because the tumor runs out of blood supply in the central portion. Without a blood supply, the tumor cells cannot live.
In association football, where the shoes themselves are known as football boots, there are three different cleat types. There are soft ground cleats which are made for wet weather. The soft ground cleats are always replaceable, and are almost always metal, so when they wear down they are easy to replace.
This is the field hockey cleat, and the top of the shoe is a lot sturdier than a soccer cleat, and also the studs on the bottom, this is perfect for a field turf situation. Either way, with both sports you're gonna do a ton of running, and a soccer cleat works well for both of them.
