Pebble in My Shoe? No, a Grape

Dang! This little grape on my foot hurts. It didn’t yesterday. Now it does. Strange one, this. My usual blisters are white. Or clear. This one was dark red. Wifey thought it was suppressed bleeding but why would that happen? This pair of shoes (an Adidas trail runner) has been good for me these past 6 months. Yesterday’s run was around a footy oval, on near flat terrain, mostly gravel. 16 laps of maybe 600m each. With runs to and from the oval, that was just a little over 10k. Not overly excessive. Certainly not enough to earn me a grape sized and grape coloured blister. I cant wait to get home and remove the socks to check on it…
