Is this a farming reference? Well, you can certainly try making a planter out of a shoe if you want to, but I don't think crops will harvest too well that way. I could be wrong. Back to the shoe language, an aglet is that piece of plastic at the tip of shoelaces. It keeps them from fraying so you can keep those kicks looking nice and neat.
At first glance this sounds like some illness or toe condition, like corns or blisters or something. But, no worries. A cap toe is actually what the toe or tip of the shoe is called when there is an extra strip of leather covering it. The cap toe can exist in sneakers, dress shoes, boots, and more.
No, this is not some sort of device for back injuries. Hopefully, you know how to walk in your shoes well enough to avoid one of those. If not, that lesson's for another instructor, not this one. LOL When speaking shoe, a slingback is any shoe with a strap at the back of the heel or ankle to hold the foot inside. These can be sandals, heels, or various styles, such as crocs. Slingbacks can be worn by women or men, depending on the shoe.
