A shoe attachment device comprises an attachment element and an attachment base. The attachment element is connected to a vamp or a heel strap. The attachment base is embedded in the sole, and includes an insertion slot into which the attachment element inserts to attach the vamp or the heel strap to the sole. The insertion slot includes an inner blocking member onto which an arcuate groove is defined. The engagement tooth engages the arcuate groove to attach the attachment element to the attachment base. A guiding lip is further formed in the insertion slot to engage a corresponding stop slot.
