A brief review, having owned Salomon GTX for ~18 months.
Pros : relatively light; comfortable & supportive; durable.
Cons : there are some significant design faults, all relating to the kevlar laces, which are abrasive :
1. They quickly wear out the plastic 'cleats' on the laces themselves, resulting in the laces slipping and the shoe loosening on your foot.
2. Despite Cotswold stating that laces would be replaced, if required, for the life of the shoe, this has not been easy (the first replacement involved a member of Cotswold staff attempting to 'weld' the end of the laces together using a cigarette lighter, but kevlar and nylon melt and burn…).
3. Of the eight eyelets on each shoe, six are metal. The two nearest the toe are a nylon loop, which the kevlar laces eventually cut through as they are abrasive. Result : shoes that are still perfectly usable that have to be thrown away of repaired. Cotswold has not been helpful and have directed me to Salomon.
4. Replacement laces are not always available - I have been waiting for a week for another replacement pair, and am having to chase Cotswold to get some into stock, even offering to pay for them.
The kavlar laces and quick tighten-release mechanism seemed like a good idea, but I would most likely avoid next time. Great idea, poorly executed.
