These insoles provide little to no support. I have custom made orthotics but needed ones that are a little more flexible for certain shoes. These got such great reviews so I figured it was a no brainer. As soon as you put weight on the insole in collapses and flattens - no support for your arch. I weigh 115 so it's not like it's due to my weight. Also, I've been battling a very stubborn knee problem and now some feet problems, hence the reason I'm wearing orthotics. If you are looking for something to put your foot ankle and knee into alignment and you have high arches, these are not for you.<br /><br />Needless to say, I reached out to the seller (Surgical Medical Source) for advice on possibly purchasing another pair that would work better for my foot and they were zero help, not friendly and dismissive. Zero stars for customer service. I will never purchase from them again.
