bought these off ebay from a link someone posted on here so unsure of the exact number of miles as the seller didn’t mention in the listing, but if I had to estimate probably somewhere around 50-60. They’re just too small for me unfortunately despite trying to squeeze into them for a run. Picked these up for $46 + shipping, and added another 4 miles, so $45 seems fair to me but willing to discuss other prices if shipping is reasonable 🤙
