Roundwood park Thursdays

If you train at Roundwood on a Thursday in the school gym the floor is waiting to be resurfaced and is now not the best to train barefoot on. We have asked about an alternative hall but they have nothing available therefore until the floor is mended can all students bring and wear suitable trainers/plimsoles at the lesson. No flip flops or loose shoes ie crocs as may slip off or cause injury.
Many thanks
