Most companies producing SPD knockoff pedals tend to get their pedals all from the Wellgo factory. Generally speaking, these pedals all use the same binding design copied from the original Shimano PD-M737 of old and thus they will work with your Shimano cleats. Besides, they'll probably come with cleats and you can use them if you so desire. I would add however that you want to be careful if they're Ritchey pedals. Some Ritchey pedals use cleats which are similar in appearance to Shimano's but are slightly incompatible. You'll be able to clip in but you won't be able to clip out.
