must-have ! 【ample】Balance Core Sneakers 3 BEAXIS (Beaxis)

Ample sneakers with the tagline "only wear them and walk to awaken your core."
They seem to add about 4-5 centimeters to your height.
I bought them for the gym, but I think they have a high design quality for everyday wear as well.
Below is the 【ample】 official website, so please refer to it for specific product details such as the expected effects.

▼Color/Size
Black / 3L (26.5-27.0cm)

I usually wear 27cm sneakers.
These shoes feel a little roomy in the toes, but there were no problems using them.
Since they have laces, I think it's okay as long as the opening has a good hold.
However, as mentioned in the reviews, they are quite heavy. Perhaps this is the necessary weight for core training.

▼Product Condition/Usability
The condition is clean as shown in the photos, but I have used them twice as gym-only shoes.
Part of the heel (see photo) has worn away on the treadmill, but if you can accept that, the condition is extremely clean.
I washed the soles with a sponge before listing them, so various faint white fiber debris is visible in the photos...

▼Reason for Listing
I want to run on the treadmill with lighter shoes, so I decided to list these.
