4 10 is a classic retro running shoe of New Balance, which is not suitable for particularly strong sports, because the sole material is thin, the technical content is not high, and the protection and shock absorption are not as good as other shoes. Walking and pressing the road should be no problem. Look at the particles on the sole and you will know that it is not suitable for sports with particularly heavy wear. What a horrible thing it is for particles to be ground flat. So it must be mainly low-intensity indoor or floor exercise. I'm afraid the only sports I can think of are gym sports or amateur table tennis and aerobics.

The midsole is divided into two layers, one is ordinary foam, that is, EVA, and the other is IMEVA. Injection molding EVA IMEVA is formed by injecting EVA into the reverse mold of midsole, and its molecular structure is relatively uniform. If this material is injected into the sole, it will be more able to withstand pressure. IMEVA's midsole is better than C-CAP? The midsole is stronger and harder to tread on.

Hard rubber outsole is said to be durable and wear-resistant, but Ndurance wear-resistant black rubber patented by NB is not used, and the result and effect can be imagined. In short, wear and tear will be the problem of this shoe, and of course it depends on your weight.

There should be no problem with the ventilation of the upper.
