Description

M's G4 PRO Powerlock Boot

The most advanced wading boot on the water, G4 PRO® Powerlock Boot – Vibram offers supreme durability and superior grip thanks to state-of-the-art materials working in lockstep with the new Powerlock cleat system for on-the-fly traction customization.

The Powerlock cleat system offers on-the-fly traction customization. Boots come with thermoplastic rubber (TPR) cleats installed and 14 aluminum cleats for added traction on rocky streambeds.

Vibram Idrogrip outsole with built-in Powerlock system for quick and customizable traction adjustment
Dual density EVA midsole for comfort
Includes two sets of cleats and cleat wrench: 14 G4 PRO® Powerlock Aluminum Cleats and 14 G4 PRO® TPR Cleats
TPR cleats should be installed when Aluminum cleats are not in use. Never use the boot without one or the other cleat system installed.

Maintenance

Here are some tips for getting the most out of your G4 PowerLock Wading Boots.

Never use the boot without either the orange TPR cleats or aluminum cleats installed. The TPR cleats are deck friendly. The aluminum cleats are your go-to for maximum traction. Don't leave home without one or the other installed.
Use the provided "ripper tool" wrench to remove and change cleats.
Use two hands on the wrench, pushing down with firm, even pressure on the ring while turning the wrench. For felt sole wading boots, this is particularly important to seat the cleats properly.
There's no need to overtighten. You'll feel the cleat engage. Follow the steps outlined here and you'll have no problem.
When removing well-worn cleats, use the tool - there are three indents around the outside of the cleat that will make this possible even on the most well-worn cleats.
