Thank you for viewing. I haven't worn these more than 10 times after purchase. Therefore, there is almost no wear on the sole (heel). There are no tears in the Gore-Tex sheet on the inside. Unlike regular sneakers, they won't get wet easily even in the rain. Also, since the surface is canvas, light colors will show dirt, but dark colors have the advantage of not showing dirt as much. The midsole is cream-colored from the beginning, rather than yellowed. The GTX series is sometimes sold, but it always sells out quickly, and the number of available items seems to be small now. Please consider this opportunity.
