can't resize woocommerce catalog images

My website:- https://www.socialandtraffic.com/

I have tried woocommerce images settings but not works.

So, I have reduced single product images size by using the below css

.single-product .images img {
width:auto;
max-width:65%;
}

Now i would like to reduce size of catalog images (homepage). Please help me how to do that

I am using virtue theme (Free version)
