.......very poor foot support and not up to the job of walking anywhere with significant foot pain after a while if I do Not a patch on the Gtx vibram products from Merrill I had before. I now Seldom wear these. Bought a pair of Scarpa approach shoes to replace. A different league altogether. There Merrill's are for walking to your car, driving and wearing in the pub. Not for walking!
Seems to do the job but not at all enjoyable to drink. A friend recommended looking for a product with natural flavouring. I tried My Protein. The banana flavour is like Nesquick and not to my liking however the smooth chocolate flavour is very good and is now my preferred product.
