-Just starting athletics and unsure about the first spikes.  

If you're unsure about choosing your first spikes for track and field, this is the one! It's recommended for those who want a solid rebound from the ground! It's a spike that anyone can easily wear, so I don't think you'll regret trying it on! You can attach a dirt pin, so you can wear it for practice on the school grounds.

Features

Soft upper that is friendly to beginners

This spike is designed as an entry model for beginners in track and field.  
The upper is mainly divided into two parts: the forefoot and the midfoot.  
The forefoot is wrapped in synthetic leather, which firmly holds the foot during landing, addressing the common braking issue for beginner athletes, while also enhancing the shoe's durability.  
The midfoot is woven with mesh and leather materials, designed to maintain the comfort of the upper shoe rather than focusing on lightness.  
It also has good breathability, so I believe you can run comfortably without excessive moisture during summer practices.  
However, it is heavier compared to other spikes' uppers, and the fit is standard for spikes.

Softness comparable to up shoes

The foot width is slightly wider.  
The fit around the heel and tongue is standard, providing a fit comparable to Asics up shoes.  
Since it maintains a feel similar to up shoes, the fit may be inferior compared to other intermediate to advanced level spikes.  
Additionally, if the heel is small or the foot width is extremely narrow, it may not fit adequately.  
Because it can be worn with the same sensation and size as up shoes,  
those purchasing spikes for the first time should consider them based on the same criteria as up shoes.  
In contrast, athletes accustomed to intermediate to advanced spikes may find the fit and lightweight characteristics lacking and may feel dissatisfied.

Spikes that prevent injuries

The pins are replaceable, with a configuration of 2-2-3 from the toe, totaling 7 pins.  
You can change to the optimal pins based on the style of the ground, such as an all-weather track or dirt track.  
The sole has a relatively flat structure up to the heel, providing very stable ground contact.  
Moreover, this sole is designed with flexibility in mind, resulting in a weaker rebound compared to other spikes.  
However, it is slightly harder and thicker than up shoes, allowing for a relatively stronger rebound compared to up shoes.  
While it offers high stability and flexibility, it may feel heavier compared to other spikes.  
I recommend this for those starting track and field.

Entry-level spike sole

Elite models generally have no curvature, and the effort is consistently transmitted; the sole has a relatively gentle curve and is flat.  
However, the toe area is slightly raised, supporting weight transfer during ground contact.  
Additionally, due to its flexibility, it allows for a strong push against the ground during takeoff, reducing fatigue.  
Compared to other intermediate to advanced spikes, the rebound is weaker, but beginners may feel it is stronger.  
Athletes at the beginner level in track and field tend to land on their heels during sprints, so the heel area is designed to be lightweight while incorporating cushioning.
