Protect your work and bring air bubbles out of applications with this pair of unite spiked shoes. The lace up metal lets you work in ease and comfort. The flexibility of the base of the shoe creates a more natural movement when walking. Thirteen 3/4" steel spikes (overall length) are precisely positioned around the metal base of the sandal for balance when walking on epoxy, sealers, gunite, and shotcrete materials. The back of each shoe has a stop to prevent work boots from moving around the shoe. Metal clasps secure straps to minimize loosening that occurs with metal closures. The overall length of shoe is 12". Use with work boots for safety. One size fits most. Sold as a pair. For best results tighten spikes before use.
