These Women's Patagonia Advocate Skimmer Shoes drop from $70 to $19.98 and further to $18.98 with code ISLAND5 at Island Surf. Even with $4 in shipping, that's $14 less than a 2-day deal we spotted and $26 less than the next-best every day deal (but they are nearly sold out of everything except size 9). These exact shoes currently start at $54 on Amazon. They feature a back pull-tab so they attach to your pack and are easy to slide on. You can also feel good about your purchase because they are made from recycled materials. Sales tax is not charged in most states.
