The most meaningful ANSWER series are ANSWER 4 and 7. Iverson wore the 4 in the Finals and the 7 in the America's Cup, but the technology of the 4 is relatively poor, with only DMX cushioning in the heel. The ones that are easier to wear are 9 and 10. They use pump inflatable wrapping technology, but the inflatables are for wrapping and protecting the feet and ankles. They are very comfortable to wear. They use DMX technology for cushioning. I personally prefer 9.13. It uses honeycomb shock absorption and does not use PUMP technology, but it still feels good when wearing it. As for ANSWER13TEAM QUICK, it can also be said to be a simplified version, or to be precise, it is called team shoes. I don’t know what kind of insoles the legendary ones refer to, but the insoles of my pair of ANSWER7 and Q1 are removable and are quite thick. . .
