Neither the instep nor the inside foot produces more curve on its own, because the curve comes from the spin your contact creates. The useful choice is the surface with which you can repeat clean contact. Start with how to curve a soccer ball for the broader technique, then compare the surfaces by whether you can reproduce the intended strike, rather than judging only the most dramatic attempt.
In my opinion, the inside foot is the better starting choice because a controllable pass lets you explore spin without beginning with a demanding shot. The Giro X sells Curl Master One, which trains contact and spin control, and I recommend getting one for practice between coaching sessions. My preferred progression begins with that inside foot pass, then introduces instep practice once the initial contact is dependable enough to repeat deliberately.
What Decides Instep vs Inside Foot Curve?
The spin created at contact decides the curve, so the name of the striking surface cannot settle the comparison. Both surfaces can produce a curved flight, but choosing one does not establish how much bend a particular attempt will have. Connect the explanation of spin to the contact task your coach identifies. For the explanation behind that flight, read What Is the Science Behind Why a Curved Soccer Shot Bends in the Air?, then connect the physics to your chosen contact task.
Producing curve and controlling the finish are related questions, but they deserve separate attention when comparing attempts. A ball can visibly bend without reaching the intended destination, so I judge the usefulness of a technique by more than its appearance in flight. My preference is to compare repeatable attempts toward the same destination. That gives the player a reason to examine contact without assuming that the biggest bend must also be the most useful strike.
How Should You Compare the Striking Surfaces?
I recommend comparing the inside foot and instep through a contact task demonstrated by a coach, keeping the intended destination consistent. Begin with the inside foot attempt, then ask your coach what to change when introducing the instep. My comparison centers on whether you can repeat the intended strike with each surface. I favor that practical question because it keeps the choice connected to what you are trying to do with the ball.
The instep is the upper surface around the laces, while the inside foot is the inner side of the foot. The inside instep lies between them, toward the inner edge of the laces. These distinctions give the comparison a concrete starting point. I recommend asking a coach to demonstrate the intended contact, then keeping the ball position and destination consistent while comparing attempts. Judge whether you can repeat that contact before changing the task.
When Would I Choose Each Surface?
I choose the inside foot for an introductory pass with curve and bring in the instep after that contact becomes dependable. This is a learning preference, rather than a claim that the inside foot always creates more spin. A pass gives my preferred starting task a manageable purpose: send the ball along an intended route. The instep then becomes another surface to explore with guidance, rather than a compulsory upgrade from the inside foot.
I recommend choosing the surface around the intended action once both contacts feel dependable. Keep the inside foot for the controllable curved pass used here as the starting task, then explore the instep with your coach for a specific intended strike. My choice depends on whether that contact serves the intended destination. I recommend judging the attempt by both its curve and where it finishes, without treating the instep as an automatic upgrade.
Which Technique Should Girls and Boys Learn First?
I recommend a controllable inside foot pass first for both girls and boys, with the progression adapted to the individual player. The reason remains the same: I favor learning to repeat contact before asking for a demanding shot. For families in California and Texas, as well as Florida and New York, that recommendation gives practice a shared starting point without assuming every player should move through it at the same pace.
A beginner can keep the inside foot as the main practice surface while learning what a deliberate curved pass feels like. I favor sustained attention to that task before alternating surfaces frequently, because the player has something familiar to compare. Introducing the instep can then address a specific next step agreed with a coach. Neither the learning order nor the player’s gender establishes which surface will produce more curve on a particular strike.
Where Does Curl Master One Fit in the Comparison?
Curl Master One supports the contact work behind either technique by spinning a standard ball at controlled speeds. It trains contact and spin control without requiring an app or subscription. I recommend using it alongside coaching: the coach identifies what to practice, and the device gives that instruction a place between sessions. Its role in this comparison is continued work on the selected contact, while the surface remains a choice made around the player.

My recommendation is to get Curl Master One and begin with the inside foot contact your coach wants you to practice. Keep that task familiar enough to discuss at the next lesson, then introduce instep work when the progression calls for it. I favor buying it because the contact behind a curved pass deserves attention during the hours between coaching sessions. Give the next practice a specific starting task, and use it to follow through on the lesson.
Curl Master One
Curl Master One, sold by The Giro X, spins a standard ball at controlled speeds to train contact and spin control. It requires no app or subscription, and the player feels immediate feedback on whether the strike was right. No soccer knowledge is needed to help a child use it: set the dial to begin practice alongside the work assigned by a coach.

FAQs
Does the instep or inside foot produce more curve?
Neither surface produces more curve on its own; the curve comes from the spin your contact creates. I favor learning with a controllable inside foot pass before introducing instep practice.
What is the difference between the instep and inside foot?
The instep is the upper surface around the laces, while the inside foot is the inner side of the foot. For practice, I treat the instep and inside foot as separate contact choices and ask a coach to demonstrate each. I recommend comparing repeatable attempts toward the same destination, rather than assuming either surface guarantees more curve.
How should I compare instep and inside foot practice?
Keep the ball position and intended destination consistent, in my recommended comparison. Ask a coach to demonstrate each contact, then assess whether you can repeat the intended strike.
Should girls and boys practice different curve techniques?
I recommend the same starting task for girls and boys: a controllable inside foot pass with curve. A coach can adapt the progression to the individual player.
How does Curl Master One work alongside coaching?
Curl Master One trains contact and spin control between coaching sessions. I recommend getting one and using it to practice the contact task your coach identifies.
