Football / Soccer shoes can be classified into 3 types
Indoor shoes (designed for playing indoor courts and fields, they are actually flat-surfaced, low-cut shoes with a slightly harder surface area than a traditional sneaker.
Turf shoes (contain various raised patterns on the bottom, for use on harder outdoor surfaces and on artificial turf.)
Outdoor shoes (Cleats-provide a player with enough amount of traction preventing him/her from slipping and giving him an opportunity to turn, stop and accelerate with ease.
Cleats can be segregated by the various field conditions they befit:
Hard Ground (HG) - for playing on hard fields. Short studs, usually evenly distributed across the entire outsole. Circular, hard rubber studs are the most effective for HG as they provide enough amount of traction without applying too much pressure on your feet and causing discomfort when your cleats are unable to dig into hard ground.
Firm Ground (FG) - for playing on firm fields. The most common universal types of soccer cleats as most of soccer fields are firm.
Soft Ground (SG) - for playing on soft fields. Almost all soccer cleats for soft pitches have detachable studs or stud's tips.Replaceable studs could be a circular or blade shape. They come in different lengths, so you can adjust your soccer shoes based on the condition of the field.
No matter what sport you play, the right footwear is extremely important . Especially so in this case because football is played on so many different surfaces -- having the right boot or shoe with the right type of traction can make or break your play and performance.
