Add extensions to your PEET dryer to safely dry taller boots, hip boots and even chest waders! There must be at least 6 inches of clearance between the top of your footwear and the base of your PEET dryer. So, when you want to dry taller boots (over 10-in tall), hip boots or waders, use one pair of 12-in extensions for hip boots and two pairs of 12-in extensions for chest waders.
