Use woven grass to make some footwear. Congrats, you've got a pair of straw sandals! You could also just call these zori sandals, since there's not really an English equivalent.

Zori are Japanese sandals traditionally made with woven rice straw (hence the name), though plastic and rubber ones are common too these days. You wear them flip-flop style, with a thong passing between the toes to keep them secure.

This jukugo word uses on'yomi readings, but the そう reading for 草 becomes ぞう for some reason, so here's a mnemonic to help you remember it:

Straw sandals are often worn by zombies (ぞう). Zombies are undead, which means they've been around forever, which means they're still wearing centuries-old traditional zori sandals. Would it make sense to see a zombie in Air Jordans? No. Real zombies wear zori.
