So disappointed. having worn my old trainers for years, I thought I should get my feet properly assessed and purchase a quality pair of running shoes. Having had a gait analysis, I purchased a pair of asics gel kayano 18 shoes and after persevering for 3 weeks I am going to return them to the store under their 30-day guarantee. After running in them for 20-25 mins, I begin to get numbness/pins and needles in the toes area. After approx 30-35 minutes, it feels like my foot from my toes back to half-way along my foot is in a vice. Whatever it is in the base of the shoe (I would guess to correct the over-pronation), digs into the underside of my foot. So, so uncomfortable.
