Shoes, surfaces, and the shin question

Running is the cheapest sport there is, right up until you read a shoe review. Here’s the short version of a very long conversation.

Buying shoes

Go to a shop that lets you run in them. Pick the pair that feels unremarkable - not plush, not springy, just unremarkable. Comfort at the moment of trying them on predicts injury risk better than any gait analysis a shop will sell you. Buy the boring pair, in your size plus a little for swelling, and stop reading.

Rotate two pairs if you can afford it, replace them when the midsole stops feeling springy rather than at some magic mileage number, and ignore anything with a carbon plate for at least a year.

Surfaces

Softer is not automatically better. Trails are kind to your joints and unkind to your ankles; treadmills are consistent and slightly dull; pavement is fine, which tends to surprise people. What matters more than surface is variety - the same route at the same pace every session concentrates load in the same places.

The three aches

Shin pain spread across the front of the lower leg usually means volume grew faster than your bones adapted. Cut the run segments by a third for a week and it resolves. Sharp pain in one small spot does not - that one gets a professional.

Knee pain around the kneecap is almost always a hip and load-management story rather than a cartilage story. It responds to slower pace, shorter steps, and squats.

Achilles or heel pain first thing in the morning is the one to respect early. Back off, add calf raises, and stop pushing pace on hills.

An ache that improves as you warm up and doesn’t limp you home is usually adaptation. An ache that sharpens as you run is information.
