Spark Plug Wire Boots

[Damien8086]

Is there any reason to use 90 degree spark plug wire boots over straight boots?

I had bought some of those spark wire boot socks which are supposed to help protect the wires/boots from the heat from the headers, but it's pretty close to impossible to slip them over 90 degree boots.

Better yet has anyone see spark wire socks for wires with 90 degree boots? Most say that they work with them, but I am finding it very difficult to slip them through.
