What to wear on a rainy commute
Build around the part of the route you cannot change: the stretch outside. A six-minute walk to a station and a forty-minute walk to work call for different shoes, even when the forecast shows the same rain icon. Map the walk, the crowded transport and the place where your outer layer can dry.
Start at pavement level
Try a familiar grippy closed shoe, straight trousers that clear the pavement, a work top and a shell you can remove at the door. Wear the actual shoes while checking the hem: a trouser that sits neatly over a boot can trail over a flat. If your route includes standing water, choose footwear suited to that depth and carry office shoes only if you have a convenient place to change.
Make the transition easy
Use a layer that still works when the shell comes off. On a warm train, open or remove the shell before you overheat, and keep a separate place for a wet umbrella. If you carry a backpack, try the shell with the bag: straps can pull the cuffs up or make the hood hard to turn in.
Check it tonight
Put on the bag, look over both shoulders and walk down a step. If a hood blocks your side view, adjust it before crossing roads. If the hem catches your heel, swap trousers rather than hoping a different pace will solve it.
