Wearing my dedicated wam'ing champion sk8tr sneex in pressed winemaking grape slop Friend makes this at home every year and we compress it into the bin to fit. So on goes my old trusty size-12 sneakers! Stomp on an press it all down flat using my feet and weight into the discard bin where it's later used for compost. It's very messy, environmentally friendly and an excuse for great fun to do! Wear them sockless so your bare feet inside take on a nice shade of blue as a bonus afterwards! (grin)
