| Zusammenfassung: | The present invention relates to a roller type wear resistant shoe palm. The shoe palm includes the vamp at the upper part of the shoes, the uppers at the middle part and the sole and heel (1) at the lower part. A rotary roller (2) is installed at the position nailed with a show palm at the rear of the sole or the heel (1) of the mentioned roller-type wear resistant shoe palm. Comparative tests for a long period of time prove that the service life of the roller type wear resistant shoe palm can be increased by around 10 times of that of the former flaky shoe palm, thus eliminating the trouble in nailing the shoe palm, reaching the satisfied effect of not changing the shoe palm with only one time of use and creating very great convenience for users. |
