Granger\'s G30 Stability insoles help adapt the flat midsole of your footwear to the shape of your foot. Their distinct shape helps to support the foot, while their deep, structured heel cup provides comfort on every step of your journey. They help to provide maximum comfort and support - from a flattened area beneath the big toe that takes up less space (and reduces pressure), to a contoured profile to help support the arch of your foot. The moisture wicking microfibre top sheet keeps your feet dry, while a felt base improves your insoles\' durability and breathability. Memory foam latex gives you enhanced shock protection. They have a contoured profile to fit all types of medium-to-high volume footwear - from running shoes, to casual footwear, to work or hiking boots.Moisture wicking microfibre top sheetContoured footbed for supportMemory foam latex for all day comfortBreathable and durable felt base
