I purchased a pair of trainers from Clarks shoes but the solid integrated arch support has severely damaged my plantar fascia. I have been unable to walk without being in constant pain for the past 2 months. I have written to Clarks but they are denying there is a fault in the design. I normally do a lot of walking and have never in over 40 years had any problems. If they felt that arch support was necessary in their trainers, surely soft, flexible ones would have been more appropriate, as oppossed to the the cheaper, rigid, solid ones they have used.
