Polysorb Crosstrainer Insole M 10-11 W 11-12 (並行輸入品)

The quality, the look and the feel is superb. I use it for my badminton shoes and it is the best. There was some glitch initially regarding the delivery but they acted fast and it reached me on time.

Spenco produces great products, I have been using them since 1970 and used them in all my shoes and boots since then, I have run many marathons over the past 54 years and trekked tens of thousands of miles, I am now 75 and have no visible wear in my leg joints. It is solely due to this product without which I would have been having knee and hip operations due to wearing out the joints through excessive exercise over more than half a century. Feel free to use this reference as you see fit. Regards Roger Barry, New Zealand

Compré para botas de hiking, cuyos insoles eran muy duros. Estas plantillas mejoran notablemente, sin perder la firmeza de la bota. No las he probado lo suficiente para opinar sobre durabilidad o manejo de humedad, pero por lo pronto muy recomendadas.

They outlasted the shoes doing 20km walking a day

I use these in my running shoes (30Km/week). They get mud-soaked every run in winter (I run in marsh forest). This has no effect on them whatsoever regarding wear and dampening. Even with this abuse, they will easily last three years (this is my third pair). Also use them in my combat boots.
