I would say ones that fit--As I know to my cost. Bought a pair of Shimano Road shoes on line that take both the 3 and 2 bolt fixings so If I did not get on with the Time pedals I could convert to SPD 2 bolt fixing. I will be going SPD as I do not like the time pedals.
But Shoes are one of those items that I like to try before I buy. The new shimano are not as comfortable as I would like so it is my fault for buying on line. I still ride MTB and the problem I find with my aggressive soled MTB shoes is that they are not comfortable to walk in. Shimano do a few MTB shoes that have a firm sole that is Rubber instead of hard plastic. Look like ordinary trainers with laces but I do prefer to have a cover over the laces- or no laces and straps.
