I was persuaded to buy some Sketchers Go Walk last year as several friends were raving about them. I must say I have been rather disappointed in them.
Basically, they are old fashioned school pumps with memory foam bottoms. (Mine are the pull-on ones) First of all I was rather shocked at the high price considering the very basic style, design and materials, but sadly, they are not the dream walking shoes I imagined they'd be. They are fine in the house and for short trips, but as walking shoes they really offer no support. They are far too soft. It's like walking on a thin sponge. Arches aren't supported at all. If it's wet the tops/seams let in water.
I can wear them without socks, which is good, but the synthetic materials mean feet and sandals get sticky/damp. They are washable though, but far from the wonderful shoes I'd been promised they were.
I'd rather wear open comfy walking sandals in hot weather I think, and buy some sturdier but light shoes for when I have to walk any distance. I was looking at Pavers in a shop recently. They look sturdier and were very light. I'll investigate them when I am next shoe shopping.
