What are the benefits of wearing cleats?
Clipless pedals create a direct and consistent connection between your foot and the pedal, which means you can push and pull on the pedal all the way through the pedal stroke. Cleats also keep your feet in a solid and consistent position, meaning that you won't have to reposition your feet every few pedal strokes.
It is the combination of the two (cleats on artificial turf or cleats on grass) that will determine things that impact performance such as level of shock absorption and step impact. But studies show that finding that right combination of cleat and surface can improve your performance by up to 20%.
But an outdoor sprint test showed that clipped in cycling shoes increased maximum power in a sprint by an average of 16.6 per cent over the trainer/flat pedal combo, while toe clips and straps added 9.7 per cent, so if you're riding harder you'll probably find a benefit from using cycling shoes and clipless pedals.
A cycling cleat is a small triangular metal or plastic wedge, which is attached into the sole of a cyclist's shoe. It is a sprung mechanism that allows the cyclist to clip their feet in and out of their pedals. To accompany the cleats, the standard bike pedals are replaced with smaller clip-less pedals.
The use of lightweight, flexible cleats on the athletic field has led to various soft tissue injuries. Athletes have gotten bigger, faster and stronger and the use of these shoes has caused them to suffer from foot pain that might not have occurred if the shoe had sufficient arch support.
Cleats and stilettos are the quickest way to damage your beautiful wood floors. Those tiny points have a lot of weight balanced on them and can cause serious indentations, along with scratches.
You can walk in cleats
they are made of a rubbery non-slip material, and they provide a flat surface for you to walk on comfortably.
You can expect one full season of kickabouts, training sessions and match days out of most cleats. From there, it will depend what material the cleat is built from (leather or synthetic) and how well you take care of them. The most frugal of us can get a good 3-4 seasons out of the right boots.
Generally speaking, cleats provide superior traction on the wet or muddy ground. However, they also tend to destroy the surface on which players are running, cutting, and making plays. It's not uncommon for players wearing cleats to send chunks of grass and mud flying as they make plays in the field.
the answer is undoubetly yes, cleats enable you to not only push down (like pedals), but pull up, push forward & back etc... So you can apply more power. If you switch to cleats there'll be minimum benefit until you build up your muscles, but when you do its a huge difference.
Are cleats necessary?
The verdict: Can you play soccer without cleats? The bottom line is that you absolutely can play soccer without cleats, but you need to think carefully about the surface that you're playing on. Soccer cleats are designed to be comfortable, safe, and appropriate when playing the game on grass.
Cycling shoes are worth it because they help improve a rider's efficiency on a bike by allowing them to exert maximum effort and achieve optimum performance, without sacrificing comfort. The shoes are made of materials specifically combined to improve the cycling experience.

You can use cycling shoes without cleats, and you can cycle any bike effectively without cleats. However, it will help to have flat pedals on your bike for an additional grip if you are not wearing cleats during your ride.
Your Shoe Isn't Complete Without the Cleat
If you want to attach your new pair of cycling shoes to the pedals at your local Spinning® studio, you will need to attach cleats to your shoes. There are a variety of different cleat styles and designs, and they are usually sold separately from cycling shoes.
Otherwise, overuse injuries are consistent, accounting for almost one third of total injuries 43 . The cleated shoe, the main equipment of the soccer player, is the interface between the player and the surface on which he evolves: as such, it represents a critical point of injury prevention.
Cleats have improved the level of play immensely. The durable little studs on the bottom provide athletes with additional grip and rapid directional change. There are different designs for cleats in sports and even some other activities. In some shoes, the studs are often removable.
Not only do they offer protection so the player is less afraid of being stepped on but the coach can use them to teach. Coaches show the player what part of the foot to kick with by telling them to use the top of the cleattop to kick the ball. No more “toe punching” the ball!
Athletes wearing regular sneakers may slip or fall on muddy or wet playing surfaces. Cleats are athletic shoes with plastic or metal studs on the sole designed to help the shoes grip the playing surface.
