Running shoes are preferred and certainly the safest. [Crocs can be a bit slippery on the climber and sometimes fall off. Please check them yourself.]
For safety reasons, children shouldNOT WEAR beach flip-flops at all due to numerous injuries we have witnessed with these sandals.
If children wear summer sandals, please ensure that they have a back-strap to keep them secure while running or climbing.
Naturally, we encourage the use of sunscreen & hats. We are outside for 40 minutes after lunch (11:35 - 12:15). And potentially 30 to 60 minutes in the morning as well as 15-20 minutes at the end of each day.
