The Aqua Lung Evo 4 Boot is a tough dry suit boot for any drysuit with a neoprene sock. The design allows for a snug fit so your fins move how you want them & the Vibram Megagrip sole is super effective at gripping wet surfaces. Evolved from the EVO3 which was used by the military the Evo 4 is practical & comfortable with reinforced panels where the greatest wear usually occurs. Mid-height laces lace up to your ankle so the boot holds your foot in position so it won't slip & rub during a dive.
