Not a complainer by trade but was so upset by the false advertising and the quality of shoes. Having a damaged left Achilles heel I did extensive research and went in headfirst and bought three pairs of Mach 4 in a few months. The first were purchased and after three months I noticed they'd both worn away completely at the back. I was injured and did not walk far at all you're talking maybe 2 km a day.
Being reasonable I put this down to bad luck/ socks (!) and again reading all their self testimony on their site of how good they were for Achilles, stupidly bought another two pairs. I walk maximum 5 km a day five times a week and within a month one of them was worn down to the plastic at the heel inside.
Not only that my physio was completely shocked and told me that these shoes had aggravated both Achilles heels. I started off with one injury and now I have both. I'm so gutted as my injured Achilles had actually healed now I'm left with two injuries. Set back big time. I just thought I was being paranoid!
The customer service was terrible because I bought them from local Mountain stores and only had a receipt for one, even though I sent them pictures and the names of the shops, they absolutely refused to help. They could see all the shoes in the photographs it's absolutely disgraceful.
Only because a huge event was in my town and HOKA sponsored it, did they even agreed to give me the money back for one pair as I threatened to go. I'm not a malicious person but I do wish I'd gone up there to protest in person whilst 7000 runners spent a week in my town
They really are terrible quality please do not be fooled. The ones I wore for a month actually have a hole right down to the plastic
