I bought of pair of real, honest to goodness birkenstock sandals. They were stupid expensive compared to the shoes I normally buy.
…now I almost never wear any other shoe. They fit, they’re comfortable, the straps dont cut into my feet now that they’re broken in, and I can take them to the store to get resoled for way cheaper than if I had continued my pattern of buying cheap sandals and running them into the ground every few months.
I went to a furry convention and spent the whole con wearing the birks with thick socks underneath.
I looked goofy as hell, but by the end of the con they were all worn in.
One thing that can help as well is rubbing a little oil into the leather wherever it makes hot spots on your feel to soften the leather a touch.
