Nail care goes beyond mere grooming to enable "maximisation of output" through physical management. This product is also recommended for mechanics who do not compromise on fine-tuning.

The Suwada Nail File is a compact 110mm long, perfect for carrying in your bag or toolbox during expeditions. It is a prized product manufactured and sold locally, and is also favoured by nail technicians.

The reason why WE recommend nail clippers and nail files is solely to help you achieve "the best performance." Why does nail management improve performance? There seems to be a scientific basis for this...

1. "Rebound force" due to nail pressure

When you push off the ground with the pads of your fingers or grip a handle tightly, your nails act as a "wall" that pushes back the pressure. This is called nail pressure. When your nails are properly maintained, the efficiency of force transmission increases, and this reaction is maximized, allowing the energy generated by your muscles to be transmitted to the object, such as pedals or handlebars, without loss.

2. Impact on instantaneous pushing (crank rotation)

When the condition of your nails is unstable, "noise" interferes with the information reaching your brain.

0.1 second reaction difference: If your nails are too long and cause pain, or if they are too short and prevent you from getting a good grip with your fingertips, your brain will judge it as "damaging" and unconsciously apply a limiter. Maintaining your nails is also the process of releasing this brain brake.

3. Grip strength and "pulling" power

Nails are also important for pulling the handlebars (e.g., during sprints).

Improved grip: When fingernails are well-maintained, the deformation of the finger pads is reduced, and the sensation of gripping the handlebars not as a "point" but as a "surface" becomes sharper. This reduces the loss of power transmitted from the upper body to the handlebars, enabling sharper acceleration. Although it's a slight difference, the condition of the nails also affects the feel of torque when using tools during assembly work. Nails play an important role for both athletes and mechanics.

To maximise performance, the following conditions are considered ideal:
Length: The same length as or slightly shorter than the fingertip - To absorb pressure while preventing interference.
Shape: "Square-off" with slightly rounded corners - To distribute stress and prevent nail breakage and ingrown nails.
Thickness/Flexibility: Not dry, with adequate moisture - To prevent cracking from impact and utilise flexibility.

In fact, some Keirin riders even apply nail polish to harden their nails. For athletes competing in explosive power and mechanics performing delicate work, nails may be a more important part of the body than we think.

Nice shoes, despite the squeak and inconsistent sizing
Size: 12, Color: Black White 05
Excellent shoes at this price point. Quite comfortable. They do tend to have a nasty squeak on tile floors, sort of like a suction cup being engaged and disengaged. I bought the navy blue and went back and bought the black. I have to say that the size varied greatly. With the second pair, I have to be sure to wear thin socks and even then, I struggle to get them on, despite having an extremely narrow foot. I'm not sure that a person with an average width foot could wear them. Buyer beware. You may need to go up a size.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.

Comfortable at First, But Did Not Last Long
Size: 9.5, Color: Cs05 White
I used these Feethit men’s slip on running shoes for about six months, and my experience was a bit mixed. Starting with the positives, they are pretty comfortable right out of the box. They are lightweight and easy to slip on, which makes them great for quick trips or casual everyday wear. The fit was true to size for me, maybe even a little on the loose side, which I did not mind for a relaxed feel. However, the durability just was not there. After about six months, I started to notice wear and tear, and eventually I got a tear in the sole right under my heel. That made them really uncomfortable to walk in, especially for longer periods. Once that happened, it was basically game over for using them regularly. Because of that, I would not recommend these for heavy use, workouts, or long days on your feet. They seem better suited for light, occasional wear rather than something you rely on daily. Overall, they are comfortable and easy to wear at first, but they do not hold up over time. If you are looking for something long lasting, you may want to look at other options.

Won’t Fit No Matter What
Size: 9.5, Color: Cs05 White, Size: 9.5, Color: Cs05 White
These shoes don’t stretch so I was unable to get my foot in the shoe. They are my size, but the opening has no stretch so you can’t get your foot in the shoe. I tried several different ways and then realized even though the shoe is the correct size, the opening was too small. They made the opening for the shoe probably the same size on all shoes, so unless you have kids feet you won’t even be able to slide them on. I’ve never had a shoe I couldn’t get on. I’ve worn Sketchers no problem. This is design flaw and I highly recommend you don’t buy!

Size: 11, Color: New Black05
These tennis shoes are so comfortable!!! I would recommend anybody to get these, especially if you do a lot of walking they’re very light but have a good heal support and the soul is nice and soft and cushy.. They’re also so cute. I got the blue ones and red also.
