Facts and Review...
A surprisingly high-quality shoe for the money. The F30i is tough and comfortable, while not going overboard on bells and whistles the way the F50i may have done.
The Sprintskin is tough, but it cushions your foot and provides for a great deal of support. The synthetic is also backed by another layer of material just underneath to reduce the occurrence of blistering and tearing of the material.
The outsole is a bladed stud pattern that's lightweight, but doesn't release from the turf all that well. It also has a covered lace for control and a more capably placed shot.
