These insoles are absolutely identical to the Trekmates gel insoles which sell for between £10 - £18 usually. I've had some of the Trekmates for years and they make an uncomfortable shoe, a... erm, comfortable one. They don't ever seem to wear out and having just bought three pairs of these from Aldi, they appear to me to be exactly the same things.
They also do some waffle ventilated things.
Insoles specially designed for shock absorption during sports such as skiing and snowboarding.
Choose from: Lattice - which has an airflow perspiration system helping to keep moisture away from the foot whilst providing unrivalled shock absorption, or Shock Absorbing Gel Insoles - which provide comfort due to their anatomical shape
