I found a couple of years ago can make insoles and durable material, so he used to make insoles, non-tight and durable, but also good to wear, to now also do not change, it is dedicated by the multi-layer fiber woven and synthetic rubber compounds made, divided into 3 layers, surface layer is the fiber fabric, middle layer and the bottom is rubber with heat and chemical energy in the precise combination of control, and fiber fabrics on each floor are different woven layers of synthetic fiber and natural fiber group into, the durability of the market than any of the insoles to be durable.

我早两年发现一种耐用可以做鞋垫的材料，于是就用来做鞋垫，不紧耐用，还很好穿，到现在还不用换，它是由多层专用纤织和合成橡胶化合物制成，分为3层，面层是纤织品，中间层和底层是橡胶用热能和化学能在精确控制中结合在一起的，纤织品每层都不同，纤织层是合成和天然纤维组成，耐用性比任何市面上的鞋垫都要耐用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
