I purchased a pair 2 years ago. This year the bottoms just tore apart. I called Columbia and told them what happened. I sent them photos as requested and I had a new set of boots in less than 10 days. They asked me my size and I got the boots and saw that they were 1 size lager, after reading the reviews I understand why I got 10 wides not 9 wides. They knew enough to send a larger size because of the sizing reviews. I will only buy Columbia boots from now on and would recommend the same. In this day and age you do not expect to get this type of service. It has given me faith in at least one company for now.
