Can I put theses shoes in the washing machine?

These are skechers and half of the shoe is made of cloth they are pretty white but the cloth part makes them look dirty. I was wondering if I could put them in the washer. Heres a link so you can see what they look like. http://www.skechers.com/shoes-and-clothing/women/styles/best_sellers/product/bikers_-_straightaway/wht (also will they shrink or will that only happen if i put them in the dryer)
