Italian Rubber

I've no previous experience of the EverGrind (metal flakes added to the extended wear carbon rubber ensuring that the heel strike area will last 80% longer than traditional outsoles) material but Fila was confident enough to issue a 7 month guarantee on it's Fila Open tennis shoe which uses this outsole.

If the Flow K4 sets your pulse racing, check out the Flow 6 aka "Fuyo!". I shall be posting some shots of my Flow K4 soon. I'm very excited with the shoe - certainly an excellent half marathon pair, but whether it suits me over 26 miles (and change) remains to be seen.
